She joined the lab in Spring 2022 and has since worked on data labeling and data processing of speech samples for the ALS project. Sherina is also an officer in both National Student Speech Language Hearing Association and Lang Stuttering Institute Student Leadership Organization. In her free time, she enjoys cooking, learning how to code, and playing tennis.

Sidh Pandit
Sidh Pandit is an undergraduate studying Management Information Systems at UT Austin. He is interested in using data science to build products that help individuals with conditions that affect speech. He joined the lab in Fall 2022 and primarily works on speech kinematic data processing and analysis using machine learning for the ALS and the silent speech interface projects. Sidh is also a caregiver and works at Camp CAMP, a summer camp for people with disabilities.

Emily Rangel
Emily Rangel is an undergraduate student studying speech, language, and hearing sciences at UT Austin. She’s been with the lab since Spring 2023. She wishes to contribute to research to transform the lives of individuals with speech disorders and is helping with data pre-processing for the automatic speech recognition project, data collection for the silent speech interface project, and ALS data processing. Emily is passionate about advocating for individuals with speech disorders in her daily life, and is eager to learn about the subject through her experiences with SDTL. Her goal is to attend graduate school and become a speech-language pathologist.

Zoe McKnight
Zoe McKnight is a senior studying Speech, Language and Hearing Sciences at The University of Texas at Austin. She joined the team in Summer of 2023 and works on data processing of speech samples as well as assistance to data collection.
