Alex K. Shalek

Shalek received his B.A. summa cum laude in 2004 from Columbia University where he studied chemical physics as a John Jay Scholar with Richard Bersohn and Louis Brus. He then performed graduate work in chemical physics developing arrays of nanowires as cellular "syringes" and electrochemical probes under the direction of Hongkun Park at Harvard University.[2] After, as a postdoctoral fellow, under the direction of Park and Aviv Regev at the Broad Institute, Shalek helped pioneer single-cell patterns in cellular responses to study how cells respond differently to the same condition, showing that genome-wide gene expression covariation across cells could be used to define cellular types and states, their internal "circuitry", from the “bottom-up”.[3][4][5][6]

As an independent investigator, Shalek and his lab have helped scale and simplify single cell genomics to study complex, low-input clinical specimens around the world.[7][5][8] In parallel, they have used these and other approaches [8][9][10][11][12][13][14] to help examine the causes and consequences of cellular heterogeneity across cancers,[15][16][17][18][19] infectious diseases,[5][8][9][10][20][21][22][23][24][25][26][27] and inflammation.[28][29][30]

Current work in the Shalek Lab includes both the development of broadly enabling technologies as well as their application to characterize, model, and control multicellular systems. With respect to technology development, the lab brings together areas of research in genomics, chemical biology, and nanotechnology to establish accessible approaches to profile and control cells and their interactions.

In addition to these tools with the global research community,[31] the lab is applying them to dissect human diseases, like COVID-19,[32][33] methodically linking cellular features and clinical observations. Major areas of focus include how: immune cells coordinate balanced responses to environmental stresses;[28][29][8][34] host cell-pathogen interactions evolve during infection;[8][9][10][21][22][23][26] and, tumor cells evade therapeutic treatment and natural immunity.[15][17][18][19][25][35]

From these observations and those of others, the lab aims to understand how disease alters tissue function at the cellular level and realize therapeutic and prophylactic interventions to reestablish or support human health.
