Assistant Professor, Department of Communication Disorders



I am interested in research that advances behavioral assessment and treatment of adult neurological communication disorders. Specifically, I am interested in understanding how language functioning and recovery after stroke is affected by mood and attention and in learning how to help people with aphasia transfer gains made in therapy to their everyday communication.

Chloe H
2nd Year MS SLP Student

I am from Modesto, California and I love to wakeboard, try new foods, bake, and spend time with my family and friends. I am a Senior here at BYU studying Communication Disorders with a minor in Gerontology. I recently married my best friend Levi in April and have never been happier! I love this field and the potential we have to help patients of all ages achieve the quality of life they desire. When I first started this major, the effects of aphasia and TBI on a patient’s ability to communicate quickly fascinated me, so I am beyond excited to already be involved firsthand in this facet of the field.

2nd Year MS SLP Student

I am from South Jordan, UT and I'm currently a first-year graduate student in the Communication Disorders program. I am interested in anything to do with the brain, particularly how it is involved in speech, language and cognition. I really enjoy working with individuals who have neurological communication disorders and have loved my experiences in the BYU Aphasia Lab. Some of my hobbies include playing tennis, reading, and playing the piano.

2nd Year MS SLP Student

I am from Provo, Utah and I am currently a second-year graduate student. I have been married for almost 3 years to my amazing husband, Jack. Some of our hobbies include cast iron cooking, traveling, fly fishing, and wake surfing. I chose this career path after observing the speech-language pathologist who provided genuine and compassionate care during my grandpa's stroke recovery. I have enjoyed working in the aphasia lab and I hope to carry these experiences into a hospital setting working with individuals who have had Strokes and TBIs.

I am from Grants Pass, Oregon and am a senior studying Exercise Science. I am preparing to go to medical school with the aim of becoming an otolaryngologist. I have tried a couple majors in my time at BYU, but my first was Communication Disorders. When I started going that direction, I was inspired by the cause of devoting my life's work to bettering the lives of others. It really was what motivated me to pursue medicine and become an ENT, especially when I learned the anatomy involved in the practice and took Anatomy as a prerequisite course. My time in the Aphasia Lab has helped me learn how to better serve and understand others and I look forward to more experiences to come.

I am from Provo Utah and am a Senior in the Communication Disorders major, aiming to become a Speech and Language Pathologist. I love how the COMD major ties together many things I love, such as my love of sound and music, my love of language, and my love of helping people! I enjoy fiddling, painting, learning Dutch, and trying new things! A new skill I’m currently learning is Irish dance. I’m very excited to work with amazing people and learn more about aphasia in this lab. My goal is to go to grad school to become a Speech and Language Pathologist.

I am a junior in the COMD program with minors in gerontology, family science, and music. I am from San Francisco and love being involved in research that can be applied to medical and speech therapy work.

I'm from Las Vegas, Nevada and I am in my last semester of the COMD program. My favorite things to do are sew, roller skate, and go thrift shopping. I'm currently fixated on Penguin Brothers pazookies, specifically the double chocolate one. I also could eat Indian and Thai food everyday of the week! Since beginning the program, I have always been most interested in issues typically involving the older population. Anything stroke related is very fascinating to me. After studying aphasia in various classes, I am excited to help and meet some great people while working in the lab!

Hi I'm Natalie Heinig! I'm from Dallas, Texas and love to talk Texas any chance I get! I am a current undergraduate student in the Communication Disorders program. My plan is to pursue a carreer as a Speech Language Pathologist after my undergraduate program. I was drawn to this carreer because of my passion for working with and helping people around me! I hope to be a light in other's lives as so many are for me! I find the brain very fascinating and look forward to working on the Post Traumatic Growth project in this Aphasia Lab!

I was born and raised in Clovis, California in a family of fiesty redheads! BYU was (and still is!) my dream school. I'm a senior in the undergraduate communication disorders program and this will be my second semester in the HEAAL. Working in the Aphasia lab has sparked my interest in the brain's role in speech and language. After graduate school I hope to work as an SLP in a rehab facility where I can serve and minister to post-stroke and TBI patients. I love indoor cycling and watercoloring and I dream of someday beating my husband in a game of "HORSE".

My name is Audrey Saunders and I am from Southern California! This is my second semester in the COMD program and I want to go into speech and language pathology. I love anything to do with the ocean whether it is surfing, lounging, sailing, or swimming. My bucketlist places to go are Italy, Greece, and Fiji. Being on this research team is a dream come true! I had the opportunity to work at a skilled nursing facility over the summer and loved being able to connect with the individual in the clinic.

Hi! My name is Macall Walker! I've moved around a bit, but I went to high school in Brigham City, UT. I'm an undergraduate student studying Communication Disorders with a minor in Gerontology. I love hiking, music, and spending time with people I love! I first became interested in studying Aphasia after my grandpa had several strokes which resulted in aphasia/apraxia. Although my interests in the field have broadened, I'm still super fascinated by Aphasia, and I hope to help post-stroke patients in my future career. I'm so excited to be in the Aphasia lab this year!

I am from Snowflake Arizona and grew up on Bellybutton Lane! I served my mission in the Salt Lake City South Mission. I grew up riding dirt bikes, jeeping, camping, mountain biking, and going on adventures! I love playing soccer, singing, and eating lots of sweets! This is my first semester in the Communication Disorder Program. I am very passionate about helping others and plan to get my master's in Speech-Language Pathology so I can help post-stroke patients recover and reconnect with their loved ones!

Hi I'm Mari Xela Merrill and am a sophomore at BYU. I am excited to continue in the Communication Disorders program and see where I end up. I got married in the Spring of 2023 after returning from my mission in Austin, TX and Montevideo, UY where my husband and I met. I grew up in the small town of Ashton, Idaho and miss the view of the Tetons. I enjoy beautiful, but easy, hikes, watching funny movies, and playing games with friends and family. The aphasia lab caught my attention when I learned that aphasia can be a result of a TBI and after having my fair share of TBI's I was dying to learn more.

I am from Gilbert, Arizona. Some of my hobbies include hiking, playing volleyball, eating homeade pazookies, and challenging my family in crokinole. I am a pre-communication disorder major. Previous to this last semester I didn't know what Aphasia was. However, I spent the last year working at an assisted living facility where several residents were stroke-survivors. I grew a love for my friends with aphasia and an overall fascination in how aphasia works and how treatments can significantly improve individuals lives. I am excited to work with this team to understand better how to advocate for those with Aphasia!
