About Me

I am an Assistant Professor in the Department of Computing and Software, McMaster University. Prior to this role, I was a post doctoral fellow/visiting researcher working with Professors Ridha Khedri and Bill Smyth, and a sessional faculty in the same department. I completed my PhD in Computer Science in August 2016, from McMaster University under the supervision of Professor Michael Soltys. I have a Master's degree in Engineering Science from Louisiana State University, USA, and a Bachelor's degree in Mechanical Engineering from Jawaharlal Nehru Technological University Hyderabad, India.

When I am not working I am with my two kids and family.
