Job Title: Postdoc in dynamic causal gene network from single-cell & spatial multiomic

Job Number: 80155

Location: Worcester, US

Job Description

We are looking for motivated postdoctoral researchers to perform causal inference and reconstruct dynamic gene regulatory network rewiring on large-scale single-cell and spatiotemporal multiomic datasets in [Please click the Apply button for the link or email] at the University of Massachusetts Chan Medical School. Our research covers several aspects such as statistical modelling, computational acceleration, multi-modal data integration, and biological interpretation. You will interpret state-of-the-art biomedical data with the latest theoretical and computational developments in causal inference and single-cell multiomics, benefiting from extensive discussion opportunities and nearly a decade of experiences and fresh ideas in the field.

About the position

The responsibilities include:

  • Develop accurate and efficient computational methods to infer dynamic causal gene regulatory networks across tens of thousands of genes from millions of cells in diverse single-cell and spatiotemporal multiomic experiments
  • Design robust objective metrics to evaluate and iteratively improve these methods and to compare them with existing approaches
  • Demonstrate the unique capacity of these methods in systematically generating novel biological insights not previously understood, from molecular and cellular to organismal and population scales
  • Distill these methods into user-friendly software packages
  • Disseminate these methods with written manuscripts and academic presentations

About you

We seek postdoctoral researchers with:

  • PhD degree (or expected) in a quantitative field such as mathematics, statistics, physics, computer science, electrical engineering, computational biology, bioinformatics, biostatistics, and statistical genetics
  • Proficient in at least one modern programming language such as Python, Julia, and R
  • Strong interest in gene regulatory network or causal inference
  • Ability to work independently and as part of a team
  • A track record of publications in peer-reviewed journals
    – Biomedical background not required

The following is considered a plus:

  • Experience in network inference, causal inference, network science, algorithm, genome-wide association studies, Mendelian randomization, and/or dynamical systems
  • Experience in computational, statistical, or machine learning method development in any discipline
  • Experience in GPU computing frameworks, such as pytorch
  • Experience working with single-cell, bulk sequencing, or other biological data
  • Good practice in software development
  • Strong communication skills

About the Principal Investigator

Dr. Lingfei Wang is a tenure-track Assistant Professor at the Department of Genomics and Computational Biology, University of Massachusetts Chan Medical School. He obtained his Ph.D. in theoretical physics and transitioned to focus on the causal inference of gene regulatory networks since his postdoctoral studies. His notable contributions include the development of [Please click the Apply button for the link or email], a pioneering computational method to infer causal gene regulatory networks from single-cell CRISPR screens. More recently, he developed [Please click the Apply button for the link or email], the first computational method to dissect dynamic gene regulatory network rewiring in continuous biological processes from single-cell multi-omics. This study also incorporates a novel causal inference framework that effectively accounts for feedback loops. The recent emergence of population-scale scRNA-seq studies also presents a unique opportunity to adapt his causal gene regulatory network method [Please click the Apply button for the link or email] from bulk genome-transcriptome variations to single cells.

About the Lab

[Please click the Apply button for the link or email] was opened in October 2023, dedicated to developing novel methods for inferring and analyzing causal gene regulatory networks. We primarily use single-cell and spatiotemporal multiomic datasets to uncover causal gene regulations. Besides lab projects utilizing the latest data modalities and theoretical developments, members are also encouraged to pursue their own ideas within the lab’s research theme. The lab is committed to supporting career development and meeting individual needs, such as conference participation and hybrid working arrangements. We particularly welcome people from diverse disciplines, cultures, countries, underrepresented minority groups, and disadvantaged backgrounds.
