Job Title: Postdoc in Single-Cell Multi-Omic Gene Regulatory Networks

Job Number: 92229

Location: Worcester, US

Job Description

We invite applications for a postdoctoral researcher to join [Please click the Apply button for the link or email] at the University of Massachusetts Chan Medical School. Our lab specializes in reconstructing multi-omic, multi-context gene regulatory networks (GRNs) from large-scale single-cell datasets. We are pioneers in GRN reconstruction from single-cell multi-omics, including:

Causal GRNs from Perturb-seq
Dynamic GRNs from scRNA-seq + scATAC-seq
Cell state-specific causal GRNs from population-scale scRNA-seq

We continue to push the boundaries of reverse-engineering molecular interactions from observational and interventional datasets in high dimensions. Our interdisciplinary approach integrates interpretable machine learning, statistics, algorithms, and single-cell multi-omics.

Position Overview

You will develop cutting-edge statistical models and computational methods to systematically extract knowledge of molecular interactions from single-cell multi-omic, multi-context data. As an integral part of our young lab, you will benefit from opportunities of high research independence, extensive discussions, and rapid iteration of tested ideas. If you are passionate about uncovering the fundamental principles and intricate interactions within a high-dimensional system like gene regulation, join us!

Key Responsibilities

  • Develop accurate and efficient computational methods to infer single-cell multi-omic, multi-context causal GRNs across millions of cells and tens of thousands of genes.
  • Design robust objective metrics for evaluating methods and benchmarking against existing approaches.
  • Demonstrate the unique capacity of these methods to generate novel biological insights at molecular, cellular, organismal, and population scales.
  • Distill these methods into user-friendly software packages.
  • Disseminate findings through peer-reviewed publications and academic presentations.

Qualifications

Required:

  • Ph.D. (obtained or expected) in a quantitative field such as Mathematics, Statistics, Physics, Computer Science, Electrical Engineering, Computational Biology, Bioinformatics, Biostatistics, and Statistical Genetics.
  • Proficiency in at least one programming language such as Python, Julia, R, C, C++, or Fortran.
  • Strong interest in gene regulatory networks, causal inference, or system reverse engineering.
  • Ability to work both independently and collaboratively.
  • Track record of peer-reviewed publications.
  • Strong motivation, curiosity, and high standards for research.
  • Biomedical background NOT required.

Preferred:

  • Experience in network inference, causal inference, network science, algorithm, genome-wide association studies (GWAS), quantitative trait loci (QTL), Mendelian randomization, and/or dynamical systems.
  • Experience in computational, statistical, or machine learning method development in any discipline.
  • Experience in GPU computing frameworks (e.g., PyTorch).
  • Experience analyzing single-cell, bulk sequencing, or other biological data.
  • Good software development practices.
  • Good communication skills.

About the Principal Investigator

Dr. Lingfei Wang is an Assistant Professor in the Department of Genomics and Computational Biology at UMass Chan Medical School. With a Ph.D. in theoretical physics, his research transitioned to focus on causal inference of GRNs. His key contributions include:
