Lucky Nanduri

Lucky is a second year AuD student at Northwestern University. She received her bachelor’s degree from University of Illinois at Urbana-Champaign in 2019, majoring in Speech and Hearing Science with a concentration in Neuroscience of Communication. Clinically, she is most interested in working with older adults, specifically the veteran population. She is also interested in the evaluation and treatment of vestibular sciences. Her project with the lab is focused on how older adults perceive childrens’ speech.

Elise Norrid

Elise is a graduate student in Northwestern’s AuD program. She graduated from the University of Arizona in 2020 with a major in Speech, Language, and Hearing Science and a minor in Spanish. She was inspired to pursue the field of audiology after growing up surrounded by family members with profound hearing loss along with communication disorders professionals in the form of neighbors and coaches. She joined the lab due to its clinical relevance and to learn more about the future of hearing aid research. In her free time, Elise enjoys reading, hiking, and cheering on the Arizona Coyotes.

Estrella Ortiz Baca

Estrella is a first year AuD student at Northwestern University. She graduated from Texas Christian University in 2020 with a major in Speech-Language Pathology and a minor in Spanish for the Health Professions. She became interested in the field of audiology after her aural rehabilitation patient in undergrad was a cochlear implant user. Clinically, she is most interested in working in pediatrics, but has enjoyed working with older adults during her clinical rotations at Northwestern. She joined the Hearing Aid Lab to learn more about the technology of hearing aids. In her free time, she likes to take walks through downtown Chicago, spend time with friends, listen to music, and watch Netflix.

Miles Sabine

Miles is a second year Doctor of Audiology student at Northwestern University. He received his bachelor’s degree in Speech and Hearing Sciences with a minor in Audio Engineering from the University of Southern Mississippi. Miles chose to pursue Audiology right before starting the 8th grade because he wanted a career in which he could incorporate American Sign Language. As his knowledge of the field progressed, he discovered he had research interests in amplification technology, signal processing, tinnitus, and musician audiologic care. Currently, he is investigating how the variability in the placement of hearing aids on the ear changes the vertical orientation of the microphone array, and how this variability affects amplification outcomes including speech understanding in noise. In his free time, Miles enjoys playing guitar, researching anything else that catches his interest, and driving around new cities.

Alexandria Meyer Sisson

Alexandria is an AuD student at Northwestern University. Her interests in neurological processing and communication disorders led her to complete a Bachelor’s degree in Communication Sciences and Disorders with a minor in neuroscience from Eastern Illinois University in Charleston, Illinois. At Eastern Illinois, Alexandria worked in research pertaining to the effects of hearing loss on those with cognitive impairments, as well as those suffering from various memory losses. She also worked at a nursing home and rehabilitation center. The focus on memory and its effect on hearing in the Hearing Aid Lab was what led to Alexandria’s decision to attend Northwestern. Her main area of interest is how hearing loss impacts those with dementia, as well as those with other types of cognitive impairments. In her spare time, Alexandria enjoys reading, hiking with her dog, swimming, and spending time with her husband and two cats.

Sheryl Quinn

Sheryl is an AuD student at Northwestern University. She received her bachelor’s in Speech and Hearing Science from the University of Illinois at Urbana-Champaign in December of 2019.

Sheryl’s goal is to use her fluency in Spanish and American Sign Language to provide resources to individuals who are from Black, Latinx, and/or Deaf communities. Her exposure to hearing aids at a young age really influenced her desire to join the Hearing Aid Lab and learn more about the technology and how it works from the inside out. When Sheryl is not in class or clinic, she enjoys spending time with her dog and cat, traveling, taking long walks through the city of Chicago, and watching TV.

Abhijit Roy

Abhijit is a PhD student at Northwestern. His passion for the field of hearing and sound is driven by a background in sound design and acoustical studies and a fascination for the curiosities of auditory neurology.

Outside the lab, he likes to play guitar, go on drives, and explore the surrounding areas.

Maya Reid

Maya is an undergraduate studying Communication Sciences and Disorders at Northwestern University. She became interested in the field after learning about it from a friend who wore hearing aids. She was matched with the Hearing Aid Lab her freshman year at Northwestern through a scholarship program and enjoyed it enough to stay on as a research assistant once the program ended. She is interested in research involving cognition and audiology, as well as using her Spanish-language skills to conduct research on the connection between linguistics and audiology. She plans on pursuing an AuD after completing her Bachelor’s degree. Maya enjoys playing basketball, spending time with friends and family, and listening to music.
