I am Ananya Bhattacharjee, currently a 3rd year Computer Science Ph.D. student at University of Toronto. I completed B.Sc. in Computer Science and Engineering (CSE) from Bangladesh University of Engineering and Technology (BUET) in October 2018.
I consider myself a Human-Computer Interaction Researcher. My research works focus on developing and understanding the role of technology in helping people manage their psychological well-being. I have developed several text messaging services, mobile applications, and websites to help people reduce their stress, reflect on negative emotions, and self-monitor moods. Collaborating with Mental Health America, I have closely worked with vulnerable population to understand their needs and expectations from digital mental health platforms, eventually allowing us to develop an AI-powered chat tool.
Additionally, I have conducted field studies in Bangladesh to understand how much of the existing support behavior techniques align with local people's customs and values. Working closely with a major crisis helpline in Bangladesh (Kaan Pete Roi), I have interacted with helpline volunteers and critically evaluated befriending model, one of the most common approaches followed by helplines around the world. Through my work, I aim to shift the research direction in mental health interventions from ‘individual’ to ‘social’.
My research works have been published in top venues like CHI, CSCW, TOCHI, and JMIR. My works have got Best Paper and Honorable Mention awards in CHI.
Angela is a second-year Ph.D. student and course instructor in the Department of Computer Science (CS). Angela’s research focuses on using HCI methodologies in CS education to design better interventions and understand the type of support our students' needs.

Anglea is also interested in learning about students’ experiences and struggles, including the prevalence of the Impostor Phenomenon in CS students.
I'm Fred Haochen Song, a 1st-year Ph.D. student dedicated to exploring the intersection of statistical science and adaptive learning algorithms. In my current research, I focus on developing innovative tools to measure mental health concerns in large student populations. Simultaneously, I'm working on projects aiming to optimize resource allocation through dynamic statistical methodologies. One of these involves a novel integration of Thompson Sampling and Uniform Random Sampling, designed to balance trial efficacy with rewards. Another uses allocation probability in Thompson Sampling as a benchmark to effectively identify prior differences between groups. Leveraging these techniques, I aspire to address real-world challenges in education, mental health, and cognitive science.
I am a 2nd year PhD student working at the intersection of Human-Computer Interaction, Reinforcement Learning and behavior change for good. My primary research focus is on using reinforcement learning algorithms (like contextual bandits) to optimize the interaction of users with technology. As part of Microsoft's AI for Accessibility grant, I have been working on an adaptive text-messaging system to personalize the content and delivery of text messages for the mental well-being of users, based on the contextual information of the users. Another line of work focuses on how pre-trained general AI models could augment user workflows. I aim to bridge my research in adaptive experiments with pre-trained language model research to explore the design space of self-improving and personalized conversational agents to improve the everyday lives of users. I will be interning in the Computational Social Science group at Microsoft Research this summer.
I'm a 1st year PhD student. My research interests are in developing tools and approaches to support the theory-driven and instructor-led design of instructional, motivational and self-regulation adaptive interventions in education.

Previously I was a Senior Lecturer and Jr Research fellow at HSE University St.Petersburg where I co-designed and taught courses and programs in Data Science, Computational Social Science and HCI, targeted primarily to non-STEM students.
I am a Ph.D. student in Computer Science at the DGP lab, and an affiliate member of UBC Language Sciences.

I am a second-year Ph.D. student in Psychology, focusing on people’s causal attributions for successes and failures in daily goal pursuit and their impact on subsequent actions, belief-updating, and self-efficacy over time. I enjoy delving into theoretical psychology, I care about theoretical research with real-world impact. I aim to use my work to design interventions that can help individuals adaptively interpret negative feedback and make better decisions. Outside of research, I delight in the art of dancing, reading novels, and critiquing subpar Netflix originals with my younger siblings.

Third-year PhD student in Statistics (started my Ph.D. in Sept 2021). I'm currently doing research on Bandit algorithms for randomized experiments, with the hope of understanding the performance of traditional Bandit algorithms such as Thompson Sampling and developing new algorithms that can achieve a better tradeoff between regret and statistical inference. I'm also in the Mental Health America project where we use Bandit algorithms to find text messages that can better help people with mental health issues.
Pan Chen is a first-year Ph.D. student in Computer Science who is interested in the intersection of computer science and data science. His research focuses on improving user interfaces through an adaptive experiment engine that uses artificial intelligence to personalize interventions to assist people.
Over the past year, he has developed tools to deploy course content with adaptive content at OLI, contributing to the lab's top 3 position in the XPrize Digital Learning Challenge. He is currently working on democratizing the adaptive experiment tool to make it more accessible for anyone to conduct their experiments.
Pan Chen is also exploring new ways to help students with their online homework, such as generating code summarizations using LLMs and providing an option for students to complete their assignments by speaking. He plans to conduct adaptive experiments himself to determine the effectiveness of these innovations in assisting people.
As a Computer Science Master's student, I investigate the dynamics of students using online learning tools, specifically Q&A forums. My projects focus on understanding student behaviors, exploring mindset reframing, and developing reflection systems. I previously studied Computer Science as an undergraduate at the University of Toronto Mississauga, where I gained firsthand insight into the positive impact of community recognition. My research investigates barriers to representation in online spaces, particularly for students seeking help and for students who need representation/role models. By exploring ways to reframe student mindsets and set expectations, I hope to find new ways to support computing programs and their students.
During my undergraduate studies, I was fortunate enough to receive support from both the NSERC USRA and MCSRA awards, which allowed me to pursue research in my field. As a graduate student, I am grateful for the QEII-GSST award, which has been instrumental in supporting my current research.
Outside of work, I enjoy reading books about aliens pretending to be human, indulging in Chinese cuisine, creating memes, and having deep conversations about existence and consciousness with my friends.

I am a first year Psychology PhD student interested in pursuing topics such as neuropolitics, automatically delivered mental health interventions, and opinion formation/maintenance. I have a diverse research background, having worked in allergy research at the Montreal Children’s Hospital, negative urgency/emotional regulation research pertaining to disordered eating at the Biopsychosocial Examination of Eating Patterns Lab, and on projects pertaining to implicit racial bias through independent collaboration with faculty at McGill University. Outside of my research interests I enjoy an array of history podcasts, going to the gym, and playing Dungeons & Dragons.
I combine the power of large language models, the IAI lab’s MOOClet framework for Adaptive Experimentation, and open education resource platforms to create a better learning and teaching experience for diverse populations. I envision open education resources that are easy to use, personalize explanations and interventions to students, and make it easy for instructors to identify the best teaching techniques for students.
