ABOUT THE LIU LAB           

Jia Liu's group at Harvard brings together researchers from Bioengineering, Electrical Engineering, Chemistry, Bioinformatics, Computer Science, and Materials Science and Mechanical Engineering to develop scalable multimodal bioelectronics that integrates nanoelectronics, soft electronics, cyborg engineering, genetic and genomic engineering, imaging and computational tools to interrogate, intervene, and re-engineer intact biological systems. Specifically, we are working on tools and platforms capable of mapping and controlling multimodal single-cell activities across time and space from a statistically significant number of cells in living organisms and behaving animals with cell-type specificity. Leveraging our unique experimental and computational expertise, we aim to study the relationship between population dynamics of single-cell multimodal physiology and gene expression, and whole-organ/organism level functions and dysfunctions to address questions in the brain-machine interface, neuroscience, cardiac diseases, and developmental disorders, and develop bioelectronic tools for cell therapy.

We have openings for postdoctoral fellows, fellow/research assistant, and visiting scholar/visiting undergraduate research intern positions.  Please go to our Openings page for more details. Visiting students are expected to work in the lab for at least 6 months. 

Every year, we recruit Ph.D. students who are interested in nanofabrication, nanoelectronics, bioelectronics, soft electronics, bio-imaging, genomics, genetics, chemistry, and electrical engineering and computer science. We can recruit Ph.D. students from all the related programs at Harvard and MIT. 

We have special positions for Masters and Ph.D. students who are working in the fields of artificial intelligence, machine learning, statistics, bioinformatics, computational neuroscience, and general computational biology.
