Shreya Karippurathu Rajagopal
Shreya joined the Polk Lab in 2020 as a Ph.D. student in the Cognition and Cognitive Neuroscience. She graduated as an Electronics and Communication engineer from Manipal Institute of Technology, Karnataka, India in 2018, following which she worked as a research assistant in the Center for Neuroscience at the Indian Institute of Science, Bangalore. With her work in predicting progression to Alzheimer’s Disease in patients with Mild cognitive impairment there, Shreya became interested in studying individual differences in brain aging. In the Polk Lab, she is investigating whether a combination of neural and cognitive measures can predict the onset of Alzheimer’s disease. She is also using EEG techniques to study how neural representations of different stimuli of the same modality become less distinct with age. She is also very interested in understanding how reinforcement learning occurs in animals, and is working on a computational model of the same. In her free time, Shreya can be found experimenting with water colors, dancing or taking absurdly long walks.
Violet had joined the Polk Lab in Fall 2021 as a lab manager. Now she has joined the lab as a new graduate student! She received a Master’s degree in Education Psychology from the University of Texas at Austin in August 2021 and earned a Bachelor of Mechanical Engineering in 2013 from Tongji University in Shanghai, China. After she graduated from college, she worked as an engineer and project manager for developing the Internet-of-Vehicles and actively joined a research project on aging and memory and the effectiveness of certain interventions on Alzheimer’s Disease. She worked as a research assistant at Legare Lab at UT Austin on a cross-cultural study of children’s cognitive development and social learning. Led by her interests and passion in Neuroscience and Clinical Psychology, she wants to explore the neural mechanism of cognitive impairment and to contribute to novel interventions and therapies for psychopathology in the clinical field. She will be working with the MiND Study!
