Dr. K Uday Kumar received his M.Sc (Electronics and Instrumentation) degree from the University Science College, Osmania University, India. He obtained his Ph.D. degree in the field of Thin films metal oxide materials from Indian Institute Of Technology Madras (IIT Madras), Chennai in 2016.  He is currently an Assistant Professor at Dept.Of. Physics, NIT Warangal, India. Prior to joining the NIT Warangal, he was working as Assistant Professor at Vardhaman College of Engineering, Hyderabad for one year.  He also worked as an Ad-Hoc faculty at Dept.Of. Physics, NIT Warangal about one and half year. 

          Dr. K Uday Kumar has worked on the metal oxide thin films during his doctoral studies.  He has developed metal oxide thin films for electrochromic applications via the magnetron sputtering method. He has worked mainly on semiconductor metal oxides such as Tungsten Oxide, Indium Tin Oxide (ITO), TiO2, and other materials. Currently, He is working on applications of energy conservation and storage application.
