EastBio PhD: Artificial Metalloenzymes for Asymmetric Photocatalysis

EastBio PhD: Artificial Metalloenzymes for Asymmetric Photocatalysis

The project combines protein engineering with metal photocatalysis in Edinburgh Chemistry, supervised by Amanda Jarvis with structural collaboration from Julia Richardson. It is a 48-month competitive studentship, with overseas tuition differences covered for successful international appointees. The key scientific challenge is to turn a designed protein environment into reproducible asymmetric catalysis. The recorded project deadline is 16 November 2026 at 23:59 GMT; confirm current availability and the receipt window with the lead supervisor. An advertised funded project is not an individual scholarship offer.

Research Problem and Doctoral Work

The Question Behind the Advert

This project asks whether a protein environment can make established metal photocatalysts more selective. Light can drive useful synthetic transformations, but activating a substrate is different from controlling which enantiomer forms. The advert combines Ru(bipy)3 and Ir(bipy)(ppy)2-type photocatalysts with enzyme molecular recognition, using genetic code expansion and protein design to develop photoactive metalloproteins. Enantioselective 2+2 cycloadditions are a stated benchmark. The exact protein scaffold, attachment site, first substrate family and quantitative targets are not published. The scientific opportunity is the relationship between a designed protein environment and a measured catalytic outcome, rather than simply putting a metal complex inside a protein. Jarvis research context, Advert-cited genetic-code-expansion study.

The work is substantially experimental. Advertised training includes protein expression and purification, engineering and mutagenesis, catalysis, synthetic organic and bioinorganic chemistry. Structural collaboration with Julia Richardson includes mass spectrometry, UV-visible spectroscopy and X-ray crystallography. A plausible thesis would connect protein identity and integrity, optical behaviour and catalytic selectivity, then investigate why a change improves one property but harms another. This is an interpretation of the advertised methods, not an assigned experimental sequence or a promise of an X-ray structure for every variant. A purely computational project would need explicit agreement. Structural collaborator, Chemistry research environment.

Frontier and Feasibility

The central risk is that an optical or structural change may not produce useful asymmetric catalysis. The important doctoral skill is distinguishing effects attributed to the metal complex from those attributed to the protein environment or other explanations, rather than reproducing a favourable conversion figure. An external Lewis-group study of iridium photoenzymes for aqueous cycloaddition reported low but reproducible enantioselectivity. That is field context, not a Jarvis-team result and not evidence that this vacancy will use its POP scaffold. External iridium photoenzyme study.

The three team studies below show complementary capabilities and unfinished problems: a metal-free photoenzyme can change rate without showing stereoselectivity; a copper artificial enzyme can change the preferred enantiomer in a different reaction; and a genetically encoded metal-binding handle can change luminescence without establishing a catalytic advantage. These distinctions make the project coherent but technically demanding. More sustainable synthesis is an objective. The vacancy publishes no life-cycle comparison, reduced metal loading, industrial scale-up or achieved selectivity for its proposed 2+2 system.

Supervisors and Recent Team Research

Complementary Supervision

Amanda Jarvis is currently listed as a Senior Lecturer in the School of Chemistry, associated with EaStCHEM and engineering biology, and accepting PhD students. Julia Richardson is listed as a Senior Lecturer in the School of Biological Sciences and is also accepting PhD students. Their joint 2024 copper-enzyme paper provides evidence of an existing catalytic/structural collaboration. Richardson's school affiliation does not change this vacancy's advertised host from Chemistry to Biological Sciences. Current university titles take precedence over informal acknowledgements in theses. Jarvis profile, Richardson profile.

The first-party group page describes work spanning protein engineering and artificial enzymes, with photoenzyme-related researchers, EastBio students and alumni. This supports an active interdisciplinary setting. It does not establish the size of a student's support team, meeting frequency, completion rate, access to a named postdoctoral researcher or guaranteed beamtime. These practical conditions remain worth discussing before accepting an offer. Group members.

Three Important Original Papers

Kuckhoff and colleagues (2023): Metal-free photoenzymes

European Journal of Organic Chemistry, e202201412. This Jarvis-coauthored original study compared attachment positions for an organic photocatalyst on SCP2L, combining spectroscopy with analysis of a model oxidation. Position changed reactivity, but the study observed no stereoselectivity. Spectroscopic evidence supported singlet-oxygen formation, which the authors associated with the lack of stereoselectivity. The tested photoenzyme showed high stability overall, with small precipitation and limited performance loss after prolonged illumination; activity, mechanism and protein stability therefore need separate attention. The relevance is the team's ability to construct and evaluate artificial photoenzymes; it is not evidence of Ru/Ir cycloaddition performance because the catalyst here is metal-free. Original paper.

Klemencic and colleagues (2024): Copper artificial enzymes

Catalysis Science & Technology, 14, 1622–1632. Jarvis and Richardson coauthored this comparison of genetically encoded BpyAla and cysteine-based metal attachment in copper artificial enzymes. Structural work, modelling and protein comparisons connected tethering choices to different preferred enantiomers in a Friedel–Crafts reaction. Reported activity remained moderate; many tested protein changes did little, and detergent in structures plus precipitation in a variant complicate interpretation. This is useful evidence of mechanistic collaboration, not photocatalysis. Original paper.

Day and colleagues (2024): A dual-purpose amino acid

Angewandte Chemie International Edition, e202413073. The advert cites this Jarvis-coauthored original study of Trz, a noncanonical amino acid combining metal binding with click chemistry. Protein analytics and optical measurements supported incorporation and a change in iridium-associated luminescence after modification. The authors did not obtain the iridium-bound protein mass-spectrometry confirmation or relative click-rate comparison, and discussed possible nonspecific binding. This provides a chemical-biology platform, not demonstrated asymmetric catalytic yield or enantioselectivity. Original paper.

University, Field and Doctoral Training

Institution and Chemistry Environment

The host is the University of Edinburgh, School of Chemistry, in the College of Science and Engineering, based at King's Buildings in Edinburgh, United Kingdom. EastBio is the funding and cohort-training partnership, not a separate degree-awarding employer. The Chemistry programme leads to a University of Edinburgh PhD. EaStCHEM combines Edinburgh and St Andrews research activities; this does not establish a joint or double degree for this student. Richardson's structural collaboration is likewise not a second award. Chemistry programme, Research degrees and entry, University and UK degree recognition.

QS lists Edinburgh 35th overall for 2027. The university's official REF account reports a fully world-leading research environment for the joint EaStCHEM Chemistry submission in REF 2021, with more than 99% of outputs rated world-leading or internationally excellent. The first is a university-wide ranking; the second is a historical joint chemistry assessment. Neither measures this supervisor's mentoring or this student's prospects. More directly relevant is a chemistry environment covering catalysis, synthesis, biocatalysis and mechanistic work, alongside the specific structural collaboration. Instrument training in the advert is more concrete than a general facility list, but individual access and support still need confirmation. QS 2027, REF 2021 scope, Catalysis and synthesis.

Training, Progression and Duration

EastBio's redesigned training concentrates core activities in years one and two, with research taking greater priority in years three and four. Cohort events, thematic training and a professional-development record complement the local doctorate. The currently published 2026/27 event calendar is not a guaranteed schedule for a 2027 entrant. A 12-week nonacademic placement before the end of year three is distinct from the thesis project. It needs early planning and approval; a placement or eligible expense application is not an industrial job offer or unlimited travel funding. The advert does not identify this as an industrial CASE project. Training overview, Current placement rules.

The advert specifies 48 funded months, while the general Chemistry degree finder labels its full-time PhD as three years. These describe different things and should not be silently collapsed. Ask Chemistry how an EastBio student's registration, fourth-year research or writing-up, tuition and submission expectations align with the award. The university's code framework covers supervision, progression and assessment; the exact 2027 Chemistry review timetable remains to be confirmed. Meeting arrangements, progression milestones, interruption rules and any unfunded extension therefore remain questions for the offer stage. Programme duration, Research-student framework.

Funding and Living Costs

What the Competition Would Cover

The exact advert offers a four-year, 48-month competition-funded studentship, open to UK and international applicants. It covers a stipend and UK-level tuition, and explicitly says Edinburgh covers the overseas tuition difference for appointed international students. The current EastBio FAQ confirms the tuition top-up waiver but limits international appointments to 30% of the annual cohort. This is a real funded route for a successful international appointee, not an allocated award or a 30% personal success probability. EastBio also describes research support; its amount and allocation to this project are not published. Funding and international FAQ, Programme funding rules.

The vacancy gives no stipend figure. UKRI's current 2026/27 minimum is £21,805 per year; this is a dated reference, not a verified 2027/28 maintenance offer. The award is student funding, not an advertised salaried employment contract. The Chemistry programme's bench-fee bands are described for self-funded students and must not be added automatically to this funded student's bill. Obtain written confirmation of funded-month dates, annual increases, tuition and research-cost coverage, and what happens during interruption, extension or writing-up. Visa fees and the immigration health surcharge are excluded by EastBio. UKRI current reference, Chemistry fees context, Excluded immigration costs.

A Dated Budget, Not a 2027 Guarantee

The official Chemistry programme estimates Edinburgh living costs at £18,504 for 2026/27, or £1,542 per month. Comparing that historical annual estimate with the current UKRI minimum leaves about £3,301 a year, or £275 a month, before excluded one-off costs. This arithmetic is only a planning scenario: the 2027 stipend, rent, personal circumstances and availability of housing are unconfirmed. Deposits, flights, application-related expenses and dependants can change the result. The official outside-London visa maintenance threshold is a separate evidence requirement, not a realistic full-year Edinburgh budget. Official living-cost reference, Dated stipend benchmark, Visa financial requirement.

Current government pages list £558 for an overseas Student visa application and £776 per year for the student health surcharge. The latter is billed according to actual visa duration, which may exceed the course period; do not multiply four academic years and call that the final bill. These are present rates, not fixed 2027 prices. A sponsorship letter may help evidence funding, but admission and a scholarship do not themselves grant a visa. Student visa and CAS, Health surcharge calculation.

Eligibility and Application Preparation

Applicants Educated in Mainland China

A domestic Chinese qualification has a positive institutional route: Edinburgh's China page considers qualifications from recognised universities, while the 2027 Chemistry programme asks for a UK upper-second-class degree or international equivalent in a related field. EastBio explicitly accepts worldwide applicants and does not generally require a Master's. Chemistry's older departmental entry page corroborates chemistry or closely related honours-level preparation. A nonchemistry background needs supervisor advice. This supports eligibility in principle, with transcript equivalence, relevant preparation and the competitive funding decision still assessed individually. China qualifications, 2027 Chemistry requirements, Departmental requirements, Worldwide competition.

Do not apply the China page's taught-Master's percentage bands to this Chemistry PhD: those tables expressly cover taught routes and named MScR courses. A Chinese Master's is not automatically mandatory here, and holding one does not guarantee equivalence or nomination. Chemistry currently lists IELTS 6.5 overall with at least 6.0 in each component, excluding One Skill Retake. Other evidence and certificate validity need the then-current programme rules. English evidence may be completed later in the EastBio process if permitted, but must meet the host's offer conditions. Scope of China tables, English requirements, Conditional documents.

The practical fit is for someone willing to connect chemistry with protein work: interpret reaction selectivity, learn protein handling, and explain how structural or optical measurements bear on catalytic conclusions. Previous experience in every listed technique is not stated as a hard condition; the advert promises in-house training. Research examples that show careful interpretation of failed or ambiguous results are useful preparation, but this is not a personal assessment of any applicant.

Current Route and Timeline

Confirm the receipt window and current forms with Amanda Jarvis; the project's explicit closing time is 16 November 2026, 23:59 GMT. Its route is to email the completed EastBio form and transcript PDF to amanda.jarvis@ed.ac.uk, with referees sending the prescribed reference forms to the same address by the deadline. Do not replace this Chemistry route with another school's application portal or midday deadline. Current 2027 instructions.

EastBio allows one project application across all hosts. Use the 2027 application and reference templates, complete the anonymous EDI survey and put its response ID on the form. Two academic or professional references are required; project supervisors cannot provide them. The FAQ says an extra CV is disregarded. Non-English documents need the required translations. The EDI survey's later closing date does not extend the application deadline. Mandatory materials, References and extra documents.

Selection involves host checks, supervisor nomination and a competitive EastBio panel. The published schedule places interviews and decisions in March and says students start on 1 October; 1 October 2027 is the cohort expectation, not an exact date stated in this project's advert. Obtain the individual start date in the offer. A successful overseas applicant still needs the university's CAS and the appropriate Student visa. Chinese nationality is not on the ATAS exemption list; whether this particular course requires clearance depends on the university-confirmed subject code and individual circumstances. Neither automatic approval nor a blanket nationality exclusion follows. Selection and cohort timing, CAS and visa, ATAS conditions.

Decision, Career Relevance and Questions

Where the Training Could Lead

The combination of synthetic chemistry, protein engineering, catalysis and structural interpretation can support work in chemical-biology research, biocatalysis and molecular R&D. The nonacademic placement may help test an industry or wider-sector direction. Industrial process roles often also need scale-up, safety, economics and reproducibility skills; a successful small-scale photoenzyme result does not establish these. The government's published engineering-biology foresight report discusses interdisciplinary skills and barriers between laboratory work and adoption. It explicitly presents aspirations rather than government policy. It is not a count of current jobs, a salary forecast, a promised employer or evidence of this group's graduate destinations. Skills and scale-up context, Placement role.

Questions Before Applying and Accepting

Ask Amanda Jarvis which scaffold and catalytic benchmark would be the first focus, how much scope there is to shape the question, and how chemistry/protein training would be staged. Ask both supervisors about meeting arrangements, day-to-day support and how structural measurements are prioritised when samples fail. Clarify access to crystallography and relevant analytical facilities, rather than assuming that a collaboration guarantees instrument time. The three papers support concrete expertise but leave genuine mechanistic and stability problems for a doctorate to address. Lead supervisor, Structural collaborator, Reactivity and stability, Metal-binding evidence limits.

Confirm current availability, the exact Chemistry email route, international fee classification and eligibility with the actual Chinese transcript before committing the single EastBio application. At offer stage ask for the 2027 stipend, all 48 funded months, tuition and research-cost coverage, fourth-year registration/writing-up arrangements, interruption and extension rules, placement support, exact start date and CAH3/ATAS/CAS requirements. The remaining uncertainties are conditions to resolve, not grounds to invent a fee gap or conclude that international applicants are excluded. Application rules, International award, Programme registration, Individual clearance.

This is a scientifically specific opportunity with an established interdisciplinary collaboration and an explicit overseas-fee waiver for successful appointees. The decisive constraints are competitive nomination and cohort funding, credible readiness for experimental chemical biology, and a written account of the four-year package and registration route. The cited papers show distinct prior results in artificial photoenzymes, copper catalysis and metal-binding chemistry; none demonstrates the proposed asymmetric photocatalytic performance. No personal admission, funding or immigration probability is estimated.

Evidence and Sources

The cited papers establish specific prior results but do not establish the proposed system's performance. The listed deadline is 16 November 2026 at 23:59 GMT; current application availability remains unconfirmed.
