I'm a materials engineer with 5 years of industry experience in developing and benchmarking cell materials & components for lithium-ion batteries (LIB) and evaluating their performance in lab and pilot scales. I currently work at Wildcat Discovery Technologies as a lead scientist.

My expertise spans synthesis, characterization & e-chem evaluation of transition metal oxides and polymer composites for LIB electrode/electrolyte applications, electrode processing & engineering, cell assembly in various sizes & form factors, and design of a wide range of electrochemistry experiments geared towards battery applications. 

I've led customer projects on material development, electrode formulation benchmarking & optimization, and slurry quality improvement over the years and have helped customers with concept validation, lab-scale prototyping, and pilot line production. 

 

I hold a Ph.D. from the University of Illinois Chicago in mechanical engineering with a focus on materials development for lithium-ion and beyond-lithium-ion batteries. My Ph.D. research at the NanoEngineering Lab dealt with developing solid polymer composite electrolytes for lithium and magnesium batteries and evaluating their performance in lab scale.
