Robin Jephthah Rajarathinam Email and Phone Number
As a Ph.D. candidate in Curriculum and Instruction with a background in Mechanical Engineering, I am deeply immersed in exploring the frontiers of collaborative learning and multi-modal learning analytics. My journey from engineering to curriculum instruction was sparked by the challenges I observed in discussion classrooms during my teaching assistantship. The engineer in me was drawn to solving the intricate problems of educational dynamics, particularly how discussions unfold in engineering settings. This curiosity led me to cross paths with my current advisor, who was investigating these very issues, marking the beginning of my transition and setting the stage for my research in educational innovation.Transitioning from Mechanical Engineering to Curriculum and Instruction, I have been fascinated by the mechanics of learning environments and the potential of analytics to transform educational experiences. This interdisciplinary approach has enabled me to lead and contribute to groundbreaking projects such as CSTEPS (Collaborative Sketch Tools for Engineering Problem Solving), CEASAR (Connections of Earth and Sky with Augmented Reality), and HoloOrbits.CSTEPS, a tool designed to facilitate collaborative problem-solving among undergraduate engineering students, has been a focus of my research. Similarly, CEASAR and HoloOrbits highlight my interest in leveraging augmented reality to aid collaborative processes. CEASAR, an AR simulation of the night sky, helps astronomy undergraduates determine their location, fostering a deeper engagement with the material. HoloOrbits, aimed at middle and high school students, utilizes AR to teach Kepler's laws, making complex concepts accessible and engaging.My research primarily focuses on understanding the dynamics of small group learning, with an emphasis on how multi-modal learning analytics can be leveraged to optimize collaboration and educational outcomes. Looking ahead, I am eager to further explore the integration of engineering principles in educational research, with the ultimate goal of devising innovative solutions that can address the challenges of modern learning environments. I am committed to contributing to a future where technology and education converge to create more engaging, effective, and accessible learning experiences for all.I am always open to discussing potential collaborations, sharing insights, or exploring new research opportunities.

Graduate Research AssistantInvite Ai InstituteUrbana, Il, Us -
Graduate Research AssistantInvite Ai Institute Aug 2023 - PresentChampaign, Illinois, United States• Annotated CEASAR dataset involving face to face collaboration of freshmen astronomy students along with FLECKS and ENGAGE dataset within INVITE institute for confusion and conflict during collaboration. Validated a noise adaptive multi-modal neural network which uses audio, linguistic (using ASR) and video data. Implemented a cross-modal fusion with attention NN.• Implemented webGL version of HoloOrbits (Astronomy simulation) to 40 participants and obtained feedback on user experience, design improvements, and multi-user interactions. Utilized the feedback to improve activity and the webGL version of HoloOrbits.• Utilized 360 camera to capture high quality student interaction in small groups when working in HoloOrbits. Simultaneous facial recognition of every student in a small group was improved by 400% compared to traditional video capturing methods. -
