Graduate Students in Computer Science


Arghavan Modiri

Master’s Student, working on the design of mobile health intervention systems

Mobile health intervention systems combines human-computer interaction with statistical machine learning to discover how to personalize text messages to people in order to motivate them to do more exercise and improve adherence to physical activity. 

Also, studying contextual Multi-Armed Bandits (MABs) and similar algorithms and their applications in health.



Jacob Nogas

Master’s Student, generally interested in statistics and machine learning applied to HCI. For my masters, I am working on issues pertaining to statistical inference from data collected by Multi-Armed Bandit algorithms in online educational experiments. I am interested in how type 1 errors (false positives) can be controlled in adaptive experiments, and validating these methods in real world online education settings. 



Ananya Bhattacharjee
Incoming first year PhD student, currently working on technology for stress management and mental health.


Mohi Reza

Incoming PhD student, interested in HCI, education, & psychology.



Jaemarie Solyst

Incoming PhD student, focused on computer science education, HCI, & psychology. Currently working on providing support for students while solving online programming problems.



Angela Zavaleta

Incoming Master's student interested in computer science education and HCI. Currently focused on interventions to help students with planning ahead and time management, in order to motivate them to stay on track when learning online and mitigate procrastination.



Affiliated graduate students



Veronica Bergstrom

Second-year PhD student in psychology, collaborating with Goodlife Fitness to investigate whether personalized text messages can increase adherence to one’s workout schedule. In her primary line of research she investigates biases between various religious (Christian, Muslim) and nonreligious (atheist, agnostic) groups.



Hammad Shaikh

Fifth-year PhD student in economics, working on improving study habits of students on online platforms through technology-mediated interventions that leverage insights from behavioral science. To be more concrete, we evaluate the impact of varying messaging interventions that aim to induce students to do optional ungraded problems and start homework earlier in an online setting using experiments.



Nina Deliu

PhD Student in Methodological Statistics at the University of Rome La Sapienza. Research areas: Bayesian Statistics, Causal Inference, Reinforcement learning and Multi-armed bandits with applications in healthcare domains, Adaptive Interventions.
