I completed my Ph.D. in Computer Science at the University of Waterloo and held Postdoctoral Fellowships at Caltech and UC San Diego. I am currently an Assistant Professor in the Computer Science Department at Florida State University.
I specialize in artificial intelligence, with an emphasis on machine learning spanning from formal foundations to emerging applications in big data and computational media.
My research on machine learning focuses on clustering, which is one of the most popular data mining tools, applied in a wide range of disciplines, from astronomy, bioinformatics, and collaborative filtering, to game design, marketing, and zoology. All these disciplines use clustering to identify groups of similar items in data. Yet, despite its popularity, there is a substantial gap between theory and practice and insufficient interaction between the communities that apply and study clustering. My work focuses on bridging this gap through the integration of clustering theory and practice in the standard batch model, as well as the increasingly popular incremental and streaming settings for clustering big data. To learn more about this research area, have a look at my brief overview on foundations of clustering.
I am also interested in computational media and computational creativity, two related, emerging fields in Artificial Intelligence. These disciplines challenge common perceptions in computer science, the arts, and humanities by redefining the computer as a medium for creative expression. Computational media offers many opportunities to utilize the power of machine learning in new domains, including music, computer games, visual art, and dance while computational creativity challenges us to design systems that act as autonomous creative agents. These exciting new areas of research have also been used to find innovative solutions in scientific discovery and education.

Artistic Training and Accomplishments
My work in computational media benefits from extensive artistic training. I've received four years of vocal training, focusing on opera, and have studied classical piano and improvisation, as well as Meiser's acting technique.
In addition, I've written a Holocaust memoir, Running from Giants: The Holocaust Through the Eyes of a Child, which tells my grandfather's story as a child during the Holocaust. This book is currently in use in Florida public schools.
