I am a postdoctoral fellow in Dr. Cheryl Stucky's Lab at the Medical College of Wisconsin. I am broadly interested in understanding how the central and peripheral nervous systems process pain. To better understand these neurobioloigcal processes, I use a combination of in vivo and in vitro optogenetic,  

electrophysiological, behavioral, and molecular biology approaches. I am particularly interested in developing and maintaining translational collaborations with clinicians who specialize in disparate chronic pain conditions like sickle cell disease. When I'm not in the lab, I can be found in a classroom teaching undergrads, in a craft store buying supplies for my next quilt, running along Lake Michigan, or at a Third Eye Blind concert.    

 

Education + Training

Postdoctoral Fellowship

Lab of Cheryl Stucky, PhD

Medical College of Wisconsin, Milwaukee, WI

As a postdoctoral fellow in the Stucky Lab, I am studying the molecular and cellular mechanisms of somatosensation in the peripheral nervous system. I lead two research projects in the Stucky Lab: (1) understanding how keratinocytes, the most abundant cell type in the skin, contribute to an organism's sense of touch, cold, and heat and (2) identifying novel targets for treating acute and chronic sickle cell disease pain. In these complementary projects, we are characterizing basic neurobiological processes that enable an organism to sense its environment, and then assessing how these processes change in the context of injury. Training in the Stucky Lab has refined my electrophysiology (e.g. ex vivo skin-nerve recordings, in vitro patch clamping), animal behavior, and molecular biology expertise. 

PhD in Biological Sciences

Lab of Benedict Kolber, PhD

Duquesne University, Pittsburgh, PA

My dissertation examined how the amygdala, a brain region that processes emotional and sensory information, mediates acute and chronic pain. For over a decade, researchers believed that pain processing was lateralized to the amygdala in the right hemisphere of the brain; neurons in this region were activated by painful peripheral stimuli and in a reciprocal fashion, activation of this region induced pain-like behaviors in rodents. Prior to my work, it was unclear how the left amygdala participated in pain sensation. Using optogenetics, I discovered that neurons in the left central nucleus of the amygdala (CeA) are typically "turned on" and suppressing pain; inhibiting these neurons increased bladder pain in naive mice. In the context of chronic pain, these neurons "turn off"; activating the left CeA decreased chronic bladder pain in mice. My work identified chemical and anatomical inputs to the CeA that vary between the hemispheres and contribute to the lateralized functions. This research laid the groundwork for my interest in deconstructing peripheral and central somatosensory circuits. 

BS in Biological Sciences

University of Pittsburgh at Greensburg

Greensburg, PA

Graduated summa cum laude and 2011 Senior of the Year; Chemistry minor. I completed a senior research project under the supervision of Kristina Pazheoski, PhD. Using basic molecular biology techniques, I investigated the biochemical properties of the protein circadian locomotor output cycles kaput (CLOCK), a transcription factor involved in circadian rhythm maintenance.

Teaching

Instructor + Guest Lecturer + Teaching Assistant

Medical College of Wisconsin 

Milwaukee, WI; February 2018 - present

I am currently co-instructing the Neuroscience Journal Club, a required weekly course for 2nd year Neuroscience PhD students. 

I have previously served as a Teaching Assistant in:

  • Medical Neuroanatomy Lab (M1 students)

  • Foundations in Biomedical Sciences IV (1st year PhD students)

I have guest lectured in the following courses: 

  • Medical Neuroscience (M1 students; "Neuroanatomy of the Limbic System")

Adjunct Instructor

Carthage College

Kenosha, WI; September 2018 - December 2019

I taught Introduction to Behavioral Neuroscience for three semesters. Since  the class was comprised of sophomore-level neuroscience majors and upperclassmen needing a natural science elective, course material served as a broad introduction to the nervous system and the biological basis of behavior. I employed active learning strategies and fostered an inclusive, comfortable learning environment in order to increase student engagement. Highlights of the course included flipped classroom exercises to learn basic pharmacology, hands-on demonstrations to understand somatosensory processes, and case studies for learning neuroanatomy.  Check out the Fall 2019 Syllabus HERE

Adjunct Instructor

Carroll University

Waukesha, WI; January 2018 - May 2018

I taught General Cell Biology Lab for one semester. Life science majors in this course learned basic aseptic laboratory skills, examined the effects of antibiotics on E. Coli growth, and performed genetic analyses on different strains of C. reinhardtii.
