The Chu Lab — Department of Genome Sciences, University of Virginia School of Medicine
The Chu Lab in the Department of Genome Sciences at the University of Virginia (UVA) School of Medicine is seeking to fill Postdoctoral Researcher positions in computational biology and machine learning. The lab develops modern machine learning, generative modeling, and statistical learning frameworks to decipher single-cell and spatial transcriptomics data, with the goal of uncovering cellular and tissue dynamics underlying cancer, inflammation, and tissue senescence.
ROLE AND RESPONSIBILITIES
Successful candidates will lead one or more of the following ongoing projects:
- Developing neural differential equation and continuous-time dynamical models for spatial and single-cell transcriptomics to dissect cell–cell interactions and perturbation responses in complex tissue microenvironments.
- Building generative models of single-cell and spatial data to characterize cellular and tissue heterogeneity in cancer, inflammation, and tissue senescence.
- Developing next-generation deep-learning and statistical deconvolution methods for inferring gene regulation from bulk, single-cell, and spatial-omics data.
Candidates are also encouraged to develop independent research directions aligned with the lab's interests.
About the PI
The lab is led by Dr. Tinyi Chu, who joined UVA as Assistant Professor in 2026. Dr. Chu received his Ph.D. in Computational Biology from Cornell University and subsequently completed postdoctoral training at Memorial Sloan Kettering Cancer Center and Yale University. His work has appeared as first- or co-first-author publications in Nature Cancer, Nature Genetics, and Cell Stem Cell, spanning statistical method development, cancer transcriptional regulation, and spatial transcriptomics. He is the lead developer of widely used open-source software including BayesPrism, a Bayesian deconvolution framework selected as a Nature Cancer 2022 highlight. Dr. Chu's research has been recognized by a Damon Runyon Quantitative Biology Fellowship and is currently supported by an NIH K99/R00 Pathway to Independence Award (NHGRI) and substantial UVA institutional startup funding — providing a strongly resourced environment for ambitious, long-horizon methodological research.
MENTORSHIP AND CAREER DEVELOPMENT
The Chu Lab is built on the philosophy of "Mentorship as Collaboration," where trainees are valued as scientific collaborators rather than assistants. As a postdoctoral scientist in a newly established lab, you will receive individualized mentorship tailored to your career goals, defined by genuine intellectual exchange, direct technical engagement in algorithm and model development, and shared co-ownership of the science.
- Active Collaboration. The PI maintains an open-door policy, meets regularly with trainees, and is deeply involved to support their algorithm and model development.
- Scientific Independence. You will be supported to develop and lead your own research ideas with the freedom and computational resources required to pursue them.
- Grant Writing and Career Transition. Leveraging the PI's recent successful K99/R00 transition, you will receive step-by-step training in scientific writing, proposal preparation, and fellowship applications. Postdocs are supported and encouraged to apply for independent fellowships.
- Visibility. Full support for presenting at top-tier venues spanning machine learning and computational biology, and active assistance in building your professional network across academia and industry.
ENVIRONMENT
The Chu Lab is part of a vibrant interdisciplinary research community at UVA, with active collaborations across the UVA School of Medicine. The lab has full access to UVA's high-performance computing resources and core facilities supporting genomics and imaging.
Charlottesville, Virginia is a highly livable university town nestled at the foothills of the Blue Ridge Mountains, known for its excellent quality of life, affordability relative to other U.S. research hubs, and rich cultural and outdoor offerings.
MINIMUM QUALIFICATIONS
Ph.D. (or equivalent) in Computer Science, Applied Mathematics, Statistics, Computational Biology, Biophysics, Engineering, or a related quantitative discipline, in hand by the appointment start date.
PREFERRED QUALIFICATIONS
- Strong foundational knowledge in mathematics and statistics
- Proficiency in PyTorch (or equivalent deep-learning frameworks)
- At least one peer-reviewed publication in the previous area of research (not necessarily biology-related)
- Genuine intellectual curiosity for solving biological problems through quantitative approaches
- Prior experience with spatial transcriptomics, single-cell omics, or related biological datasets is a plus but not required — candidates from purely computational backgrounds are strongly encouraged to apply; domain-specific biological knowledge can be acquired on the job
This is a 12-month appointment with the possibility of renewal contingent upon satisfactory performance and the availability of funding. Salary is commensurate with education and experience.

Get Access To All JobsTips for Finding J-1 Visa Sponsorship in AI ML Platform
Document your ML credentials before applying
Assemble transcripts, project portfolios, and letters confirming hands-on experience with model training infrastructure, MLOps pipelines, or distributed compute systems. Designated sponsors evaluate technical depth when approving your DS-2019 training plan.
Distinguish Trainee from Research Scholar eligibility
The Trainee category fits early-career professionals with a degree plus one year of relevant experience. Research Scholar applies if your AI ML Platform work is tied to a university, national lab, or recognized research institution, not a commercial product team.
Target host employers with established J-1 track records
Search Migrate Mate to find U.S. companies that have hosted J-1 exchange visitors in AI and ML roles. Employers already familiar with the host-organization agreement and training plan requirements move significantly faster through onboarding.
Build a role-specific J-1 training plan early
Your DS-7002 training plan must map each phase of the placement to concrete ML skills, tools, and measurable outcomes. Generic plans are frequently rejected. Align the plan to the specific platform engineering or model deployment work the host employer has described.
Verify the 2-year home residency requirement applies to you
If your home government funded your education or your occupation appears on the Exchange Visitor Skills List, you may face a 2-year return requirement before changing status. Confirm your status with USCIS before accepting a host employer offer that assumes direct H-1B visa transition.
Confirm the host employer can execute a compliant agreement
The designated sponsor, not the employer, issues your DS-2019, but the host organization must sign a formal host agreement and designate a responsible officer point of contact. Smaller AI startups sometimes lack this infrastructure, which stalls or voids placements.
AI ML Platform J-1 Visa: Frequently Asked Questions
Which J-1 program category fits AI ML Platform roles?
It depends on your career stage and host setting. The Trainee category applies to professionals with a relevant degree and at least one year of post-degree experience in software engineering or data systems. The Research Scholar category applies if your ML platform work is conducted within a university, national lab, or accredited research institute rather than a commercial technology company.
Who actually sponsors my J-1 visa for an AI ML Platform position?
Your visa sponsor is a U.S. Department of State-designated organization such as IIE, CIEE, Cultural Vistas, or AIPT. They issue your DS-2019 form, approve your DS-7002 training plan, and monitor your placement for regulatory compliance. Your U.S. host employer is not the visa sponsor. They are the host organization where the actual AI and ML platform training takes place.
How do I find U.S. employers willing to host J-1 exchange visitors in AI and ML?
Use Migrate Mate to search for AI ML Platform roles at companies that have demonstrated J-1 hosting experience. Many employers in this space are comfortable with the host-organization agreement process because they already hire international talent, but finding ones with direct J-1 familiarity shortens the onboarding timeline significantly.
Does the 2-year home residency requirement affect AI ML Platform professionals?
It can. If your country of nationality appears on the DOS Exchange Visitor Skills List for computer science or engineering disciplines, or if your education was funded by your home government, you may be subject to the 2-year foreign residency requirement after your J-1 period ends. This affects your ability to change status to H-1B or apply for a green card without first obtaining a waiver. Confirm your situation with USCIS before finalizing any offer.
What should my J-1 training plan include for an AI ML Platform role?
The DS-7002 training plan must detail each phase of your placement with specific skills, tools, and measurable learning outcomes. For AI ML Platform roles, that typically means listing distinct phases covering infrastructure setup, model lifecycle management, experiment tracking systems, and deployment pipelines. Your designated sponsor must approve the plan before issuing the DS-2019, so vague or overly broad descriptions will delay or block your placement.
