I am working on synthesizing bi-functional catalysts for Li-air battery. The high cost of cathode materials
and low efficiency hinder the development of Li-air battery. Therefore, cheap and highly efficient
catalysts for both oxygen reduction (ORR) and evolution reactions (OER) are indispensable. I am trying
to utilize solution based methods to synthesize Mn oxides, which are potential catalysts for both ORR
and OER. The methods can be scaled up without efforts with low cost as well.

I am currently working on developing spin valve fabrication and spin transfer torque devices. The phenomena
of spin polarized current transferring angular momentum to another magnetic layer can be a basic building
block of a spin-based computing system. Also do research outside the field of spintronics. I am attempting to
supercapacitors and devices on two-dimensional materials such as transition metal dichalcogenides, and I am
studying on-chip energy storage. While working on my MS degree, I studied on-chip scale energy harvesting,
and my masterâ€™s thesis was about the design and fabrication of a vibration-based MEMS energy harvester
for low frequencies. The power of lithography still impresses me. It is amazing that billions of transistors can be
placed into a relatively small area. But Iâ€™m well aware of CMOSâ€™s limits, which is why I also find
spintronics so interesting. Spintronics has the potential to overcome some of the problems in the field by being
the foundation of a new way of creating and connecting circuits. In the end, I am a learner and a doer. I
canâ€™t imagine a career without research or without applying research. Thatâ€™s probably why I enjoy
exploring novel device concepts and fabrication Technologies--they always combine learning and doing.
