Ajay completed his doctoral degree at NTU Singapore where he worked with Prof. Tan Lay Poh to study the role of biomechanical properties in stem cell differentiation. He then worked with Prof. Michael Sheetz at Mechanobiology Institute, NUS as a postdoc. There, he found that cancer cells are mechanosensitive and selectively killed by application of mechanical forces. ​

In Nov 2021, Ajay joined the the Bioengineering Department, where his Mechanobiologics Lab works on investigating the effect of mechanical forces on cancer cell growth and in regulating stem cell fate using custom-built microfluidic devices and micro/nanoscale biomaterials.
