ABOUT


I am currently a senior research scientist at Affectiva. I received my PhD in 2018 under the supervision of Dr. Margrit Betke and Dr. Stan Sclaroff with the Image and Video Computing research group at Boston University's Department of Computer Science. I attained a Master of Science degree in Computer Science from Boston University in 2014, and a Bachelor of Arts degree from Connecticut College in 2012 where I majored in Computer Science and Architectural Studies. During my PhD, I interned at Disney Research (Summer 2015) and Adobe Research (Summer 2016).

In my spare time, I do freelance work in art and photography. Some of my work can be seen at ajjenjoshi.com.
