In an effort to maintain a sustainable and fulfilling academic career, I prioritize student mentoring, teaching, and scientific inquiry when time conflicts occur.
Prospective students interested in joining my group please read the notes at the end of this page.

My scientific work contributes to the fields of human-robot interaction (HRI), human-computer interaction (HCI), and robotics.
The research directions I am currently pursuing include:
Making robotic technology more accessible to people with diverse backgrounds.
Understanding the long-term effects of human-robot interactions in real-world settings.
Improving the quality of life for older adults using technology.
Designing effective interaction strategies for AI systems to assist people.
My research has been supported by NSF, NIH, NIST, Johns Hopkins Institute for Assured Autonomy (IAA), Applied Physics Laboratory, and Malone Center for Engineering in Healthcare.

PhD I am always looking for highly motivated students interested in human-computer interaction and/or robotics. However, I do not reply to any inquiries and/or comment on applicaiton materials. If you are interested in working with me, you need to apply to our CS graduate program directly.
MSE and Undergraduates
I am always willing to mentor and involve highly motivated MSE and undergraduate students in research. Research projects in my group typically involve substantial software engineering. Prospective students should have completed at least Intermediate Programming, Data Structures, or Algorithms for Sensor-Based Robotics before reaching out.
Research is not a hobby; it requires a strong commitment. To make meaningful progress, you should be prepared to dedicate at least 10 hours per week to your research project. Teamwork is essential, as you will likely collaborate with one or two of my PhD or Master’s students on a project.
If you believe you are ready for this commitment, please send me a note along with your resume and transcript for consideration.
