I am an Associate Professor in the Department of Computer Science at Hunter College and a member of the Doctoral Faculty of The Graduate School and University Center’s Ph.D. Program in Computer Science at the City University of New York (CUNY). My research interests lie at the intersection of software engineering, programming languages, and reliable (Machine Learning ) systems. I investigate how program analysis, automated refactoring, and type theory can ease the burden of correctly, efficiently, and securely evolving large and complex software. I also study how software developers use particular programming language constructs (empirical software engineering) and how software engineering methodology can improve statistical programs and artificial intelligence. My work has been externally supported by the National Science Foundation (NSF), the Japan Society for the Promotion of Science (JSPS), Amazon Web Services (AWS), and the Verizon Foundation.
I am currently seeking highly motivated undergraduate, master’s, and doctoral students who love to program and are interested in programming languages and software engineering research!
I am a CUNY Institute of Computer Simulation, Stochastic Modeling, and Optimization (CoSSMO) member and lead the PONDER Lab @ CUNY (flyer). I have served as a program committee (PC) member for ICSE (‘24, ‘25), ASE, ECOOP, GPCE (‘21, ‘22), ‹Programming›, IEEE SCAM, and OOPSLA’s Onward! I have sole-organized the New York Seminar on Programming Languages and Software Engineering (NYPLSE) and co-organized SPLASH (‘21, ‘22), ESEC/FSE, ECOOP, and the Hunter College Cyber Security Summer Camp for female non-CS majors. I am a mentor for NYU GSTEM and ACM SIGPLAN-M.
Originally from Edison, New Jersey. I received my MS and Ph.D. degrees in Computer Science from Ohio State University and my BS degree in Computer Science from Monmouth University in New Jersey. Before joining CUNY, I was a Software Engineer at Apple, Inc. in Cupertino, California, where I worked on Digital Rights Management (DRM) for iTunes, iBooks, and the App Store. I also developed distributed software that tests iPhones, iPads, and iPods. You may also find more information about me by visiting my CUNY Academic Commons profile, vita, and blog (you can subscribe to updates). I teach several courses and serve on several committees. In my spare time, I enjoy traveling, sports, and walking the streets and parks of Brooklyn. My favorite text editor is Vim.
