Scientist, Educator, Artist
I am a researcher at Smart Information Flow Technologies (SIFT) who also participates in various activities regarding education and/or art. A common theme across my research, educational, and artistic endeavors is augmenting interactions between people and other entities. Whether it is machines interacting with people, hands-on learning, games, etc., my goal is to provide opportunities for people to engage in new experienes and produce outcomes that spread smiles and open new worlds of possibilities.
I received my Ph.D. at the University of Massachusetts Amherst, where I was a member of Dr. Shlomo Zilberstein's Resource Bounded Reasoning (RBR) Lab---my dissertation studied how machines make decisions to interact with people naturally using artificial intelligence planning and plan recognition. During the summer of 2015, I was a visiting researcher at the University of Tokyo in Dr. Alex Fukunaga's laboratory. I was also an initial member of Dr. Sriraam Natarajan's research group during my undergraduate studies at Wake Forest University. All these experiences contributed to the development of my academic pursuits, and I find it important that others have similar opportunities to discover their passions. This is one of the many reasons I am excited to direct the Intelligent Interaction (SQU(INT)) Lab as a mentor to students curious about the world of artificial intelligence and/or human-X interaction research.
Below I provide some brief information about myself, my research, and some of my educational and artistic efforts. You can click on the bracketed phrase [...] next to each section title for more details.

My research interests lie at the intersection of interdisciplinary areas to understand how autonomous machines can interact with people in ways that feel natural: AI planning; plan, activity, and intent recognition; human-computer/robot interaction; knowledge representation; and statistical-relational methods. The broad focus of my research is the development of artificial intelligence methods for human-computer/robot interaction, aiming to develop systems that adaptively interact with human users through understanding their actions in the environment. I am also an advocate for human-aware design of human-aware AI, which explores people's variances in expectations, abilities, experiences, and more when creating these intelligent systems for various applications. If we expect intelligent systems to think about people, then we scientists need to similarly consider them via incorporating HCI, HRI, and human factors engineering practices into our methodologies.

Due to the research opportunities I was fortunate to have as an undergraduate student, I strongly believe in undergraduate involvement in research. Considering the life-changing impact it had on me, I want to make sure that other undergraduate students have a chance to try it in case it would really interest them. There seem to be very few opportunities for undergraduate students to do research outside of REU Programs and institutions with small graduate student bodies.
When first starting my undergraduate career, I was planning to pursue a job in the videogame industry. I was drawn to their development by the blend of mathematics and computer science needed to program them, the creativity behind experimenting with unique play mechanics and designing the story/characters/places/etc., and the smiles that they brought to so many faces when people played. Believe it or not, research also has the blend of computer science with mathematics as well as many other areas of study, creativity to study how to bring our dreams and imaginations into reality, and the power to make many people smile. Additionally, research provides an opportunity to explore the unknown and try to develop an understanding for that which we do not yet completely understand.
I strongly believe that education is an opportunity to learn new things, grow from experiences, and discover passions. Even though present-day occupational expectations paint education as an obstacle to achieve career goals, we can make the learning process engaging and motivational beyond a requirement. Besides teaching and creating course materials, I have a history of mentoring students for their honors projects and independent studies. Check out the Intelligent Interaction (SQU(INT)) Lab webpage for the research students did directly under my mentorship.
In the Fall 2023 semester, I am the instructor for Mathematics for Machine Learning (MATH5700) at Wentworth Institute of Technology.
Since the 2020-2021 academic school year, I have served the role of client for Heriot-Watt University's Third-Year Software Project course. My responsibilities involve creating a project topic, co-writing the specifications with the course instructor, and serving as a resource to answer student questions about the topic and specifications. In the Spring 2023 semester, I was fortunate to have the opportunity to visit Heriot-Watt University in person and engage with the students as they presented their year-long efforts in an expo---it was an amazing afternoon meeting the students in person and seeing what each group created!
In the Spring 2017 semester, I was a co-instructor for Artificial Intelligence (CMPSCI 383) with Kris[tina] Fedorenko at UMass Amherst.
In the Fall 2015 semester, I was the instructor of a first-year seminar (CMPSCI 191) entitled "Introduction to Computational Thinking through the History of Videogames" at UMass Amherst.
In the Spring 2015 semester, I was the teaching assistant (TA) for Creative Game Design and Development (CMPSCI 397G) at UMass Amherst. Despite funding cuts removing the TA position formally, I continued to volunteer my time assisting in-class discussions and providing students feedback on their projects.
In the Spring 2014 semester, I was the teaching assistant (TA) for Artificial Intelligence (CMPSCI 383) at UMass Amherst.
In addition to promoting undergraduate exposure to research, I am an advocate of improved science, technology, engineering, and mathematics (STEM) education in the K-12 grade school curricula. These are the fields of the future, and we need to start introducing them to students at a much younger age. There are currently many cultural biases against them that we can easily avoid if we encouraged students to pursue STEM fields, taught younger students the fundamental skills and techniques such as computational thinking and abstraction, and removed the false stereotypes that STEM fields are "too hard to be worth trying."
Materials that I create for educational and outreach workshops/presentations are usually made available afterwards. These range from slides to tutorials and sometimes videos. The list below contains more recent resources that I produced. The complete list may be accessed by clicking [More Resources] above.
As the organizer of the 2023 and 2024 EAAI Mentored Undergraduate Research Challenges, I created some webpages sharing project ideas and resources. The 2023 page talks about Human-Aware AI in Sound and Music, and the 2024 page talks about AI for Accessibility in Communication.
I created a reference sheet for the "Writing Scientific Documents in LaTeX" workshop that shows LaTeX commands to use for common buttons found in Microsoft Word menus. The sheet may be found here.

Games serve as a controlled environment that constrains play under various rules and goals. Careful game design involves developing rules and goals that satisfy specific purposes and intents, regardless of whether they are for artistic expression, a form of entertainment, or a means of scientific experimentation. I have approached game design professionally through all my lenses. Games can serve as a vehicle for developing various skillsets in a safe, exploratory environment, and I have been designing various games and play experiences for students to learn about STEM concepts. As a means of research, I have the pleasure to exercise my game design efforts from time-to-time creating platforms that create specific experiences. Scientists can analyze the data from people playing these games; check out the video demo of Cube Crusher to see a game that I co-designed with Helen Wauck for social science research. My artwork often applies my game design experience to craft interactive experiences between people and/or the work, capturing elements of play and engagement whether the work itself is or is not a game itself.
Although I love research, education, and game design, I also enjoy international travel and learning about other cultures, playing games (analogue and digital), comic books (both Western and Eastern), and various other forms of art including, but definitely not limited to, drawing, illusionary arts (also called magic), casual photography, poetry, playing the clarinet, composing music, and contradancing. I get the opportunity to exercise most these hobbies when I create games, and I also find ways to include them into my research and lectures from time-to-time.
