Brian Callaghan, M.D.
Dr. Callaghan’s research has focused on the metabolic factors that are associated with neuropathy. He has completed four observational studies that have demonstrated that hyperglycemia, obesity, and the number of metabolic syndrome components (increased blood pressure, high blood sugar, excess body fat around the waist, and abnormal cholesterol levels), but not hypertension or dyslipidemia, are associated with neuropathy. This has led to a proposed interventional study of surgical weight loss and/or high intensity interval training to determine if either intervention can prevent nerve injury. If successful, either intervention would be the first disease modifying therapy for neuropathy. In February 2018, he published “Diabetes and Obesity Are the Main Metabolic of Peripheral Neuropathy,” in the Annals of Clinical and Translational Neurology.
Dr. Callaghan has investigated ways to improve the efficiencies of healthcare delivery within neurology with a focus on peripheral neuropathy and headache.

Sarah Elzinga, Ph.D.
Examining the bioenergetics of diabetes, Dr. Sarah Elzinga researches the underlying mechanisms of neurological complications of prediabetes and diabetes.
With an understanding that patients have low levels of systemic inflammation, changes in glucose and insulin metabolism, and varying circulating lipid concentrations, Dr. Elzinga is working to understand how in early disease these factors work together to promote further damage. Her goal is to understand how immune system pathways respond to damage at the cellular level to promote inflammation and injure the nervous system, resulting in peripheral neuropathy and cognitive decline.
Since joining the University of Michigan Program for Neurology Research & Discovery in 2017, Dr. Elzinga has utilized multiple models to examine peripheral neuropathy and cognitive decline. These models include novel 3D culture systems, developed in collaboration with U-M’s bioengineering department, that aid in the understanding of how the different cell types in the nervous system interact. Additionally, work in other modeling systems has begun to present possible treatment options for neurological complications of prediabetes and diabetes.
Dr. Elzinga has a Ph.D. in veterinary science (immunology & endocrinology) from the University of Kentucky, as well as a Master of Science in animal science from Michigan State University. She has multiple publications (5 first author and 3 co-author) and has presented her work at many national and international conferences, including the international veterinary immunology symposium, the invitation-only Dorothy Russell Havemeyer Foundation Equine Endocrinology Summit, and the American Diabetes Association.

She is also supported at U-M by the National Institutes of Health Multidisciplinary Postdoctoral Training Program in Basic Diabetes Research.
Claudia Figueroa-Romero, Ph.D.
Dr. Figueroa-Romero is a research scientist interested in the complex molecular regulatory mechanisms affecting gene expression and the cross talk between environmental factors and the genome. Her research addresses the role of post-translational modifications and epigenetics in the development of neurodegenerative diseases. She takes a multi-disciplinary and multi-collaborative approach and she employs postmortem tissue as well as animal and cellular models of neurodegeneration. Her long-term goal is to identify pathogenetic mechanisms underlying the onset of neurological disease such as amyotrophic lateral sclerosis (ALS) and diabetic neuropathy. Her findings could facilitate the early diagnosis and potentially early-stage therapeutic interventions to increase survival outcomes in patients affected by these diseases.
Dr. Figueroa-Romero’s primary interest is to investigate the contribution of internal and external environmental factors to the development of neurodegeneration. Epigenetic mechanisms such as DNA methylation and microRNAs respond to external cues to regulate gene expression to maintain cellular homeostasis and their malfunction is associated with disease. Dr. Figueroa-Romero studies epigenetic mechanisms and their transport in extracellular vesicles as biological processes leading to the development and spread of ALS. She is also interested in understanding the molecular factors that dysregulate RNA homeostasis resulting in functional abnormalities associated with sporadic and familial ALS.
She is also exploring the role of the exposome (alterations of biological systems in response to exposures to environmental pollutants) in the pathogenesis of ALS by identifying correlations between altered levels of epigenetic marks and high environmental risk scores from blood ALS and control subjects. In addition, the internal environment defined by gut microbial communities, or microbiome, may influence the gut-brain axis. The gut therefore provides a unique opportunity to study the impact of the most intimate of environmental factor, the gut microbiome, on the pathogenesis of neurodegenerative disease. Dr. Figueroa-Romero is investigating the potential role of the microbiome with aberrant expression of immune- and inflammation-related markers in ALS and diabetic neuropathy.
Dr. Figueroa-Romero has published 19 papers and has given presentations on ALS at the University of Michigan and Hope College.
Dr. Figueroa-Romero is also deeply invested in education. She is actively working with graduate students, she mentors undergraduate theses and trains high school students. She is interested in using her life experience as a Latina woman and her expertise as a scientist to contribute as role model and to recruit and mentor the next generation of minority students to become active members of the scientific community. Her efforts to develop an early second language education in elementary school resulted in the development of the “Elementary World Languages” program in the Ann Arbor public schools. She has also participated in the miRCore summer camps. She believes that investing substantial effort to develop programs between universities and young students in grades K-12 in order to shorten the distance between the scientific and the non-scientific communities will teach younger generations to love and embrace the sciences as part of their daily lives.
Dr. Figueroa-Romero earned a Bachelor of Science in biology and a Spanish-English translation certificate from San Diego State University (SDSU). She received the Minority Access to Research Careers (MARC) Fellowship, which is sponsored by the National Institutes of General Medical Sciences. She was a three-time winner of SDSU’s Biological Sciences Annual Award and made Phi Beta Kappa.

She received a Ph.D. in epidemiology at the University of Colorado-Denver/Colorado School of Public Health.
Bhumsoo Kim, Ph.D.
Dr. Bhumsoo Kim’s main research goal is to understand the link between metabolic syndrome (MetS), such as diabetes and obesity, and Alzheimer’s disease (AD). Multiple studies indicate that patients with MetS have an increased risk of developing AD.
AD currently affects 5.4 million Americans and this incidence is expected to reach almost 14 million by 2050. Additionally, more than 30 million Americans have diabetes and more than 2 in 3 adults are considered overweight or obese. Considering the strong connection between AD and MetS the incident of AD can dramatically increase without the development of the proper intervention.
By using cell culture and animal experimental models, Dr. Kim is examining how obesity and diabetes affect amyloid and tau proteins, two prominent pathological markers involved in the development and progression of AD. He is especially interested in the contribution of the insulin resistance, which is the key component of the metabolic syndrome. Dr. Kim investigates the effect of glucose and lipid, the two main factors involved in the development of diabetes and obesity, on the biochemical changes of amyloid and tau proteins using the brain neuron cells in the culture dishes. He also examines the similar changes using the animal models of obesity. Dr. Kim’s researches demonstrate that high levels of glucose and lipid induce changes similar to AD in brain neurons and also obesity and diabetes affect cognitive function in animal models. Finding common factors affected by both metabolic syndrome and AD can lead to more effective therapeutic approaches to treat both diseases.
Dr. Kim has authored 31 papers and presented 11 oral and numerous poster presentations in national and international conferences including the Society for Neuroscience, Endocrine Meeting, International AD/PD conference among others. Dr. Kim belongs to the Society for Neuroscience and American Diabetes Association.
Dr. Kim earned a B.S. and M.S. from Seoul National University in South Korea. He worked in the industry for six years before earning a Ph.D., in neuroscience from the University of Michigan under Dr. Eva Feldman. During that time he was awarded the Outstanding Student Publication Award from the University of Michigan Neuroscience Program, and the Young Investigator Education Enhancement Award from the American Society for Neurochemistry. He finished two years of post-doctoral training at the Joslin Diabetes Center, Harvard Medical School in Boston before joining the research team of Dr. Feldman again in 2000.
Alina Monteagudo, Ph.D.
Dr. Alina Monteagudo’s research is focused on the immunology-aspect of neurodegenerative diseases, specifically amyotrophic lateral sclerosis (ALS), a disease of motor neurons. Recent data from the Program for Neurology Research & Discovery (PNR&D) indicate that blood from ALS patients exhibits a significant increase in natural killer (NK) cells, a type of immune cell responsible for protecting the body and destroying damaged cells. Although these NK cells also accumulate in the central nervous system (brain and spinal cord), their contribution to ALS is still not known.
Dr. Monteagudo joined PNR&D in 2018 and is working to characterize how NK cells factor into the progression of ALS. Her specific goal is to assess whether NK cells found in the periphery penetrate the central nervous system to affect motor neuron survival and/or function during ALS. In the laboratory, Dr. Monteagudo is differentiating ALS patient-derived stem cells into neurons to probe the mechanisms by which NK cells contribute to loss of nerve function. This patient-derived model also allows her to screen new therapeutic targets against NK cells. Through this work and collaborative efforts underway with Drs. Benjamin Murdock and Claudia Figueroa-Romero, Dr. Monteagudo is uncovering the specific role of inflammation in ALS and identifying new therapeutic targets.
Dr. Monteagudo earned her Master of Science degree (2015) and Ph.D. (2017) from the University of Rochester, both in Pharmacology. At the University of Rochester, she authored three publications and earned five awards. She received her B.S. in Chemistry at the University of Puerto Rico-Rio Piedras in 2012.
Benjamin Murdock, Ph.D.
Dr. Ben Murdock focuses on the immune system and its role in the destruction of the nervous system. His primary project involves the immune system and amyotrophic lateral sclerosis (ALS), particularly the role of natural killer cells and CD4 T cells in controlling disease progression. Natural killer cells protect the body from infection and cancer, but also kill dying cells. Previous research has found that the molecule that protects the body from its own natural killer cells is missing on motor neurons during ALS, and the Program for Neurology Research & Discovery has recently found that the number of natural killer cells increases dramatically as ALS progresses. Conversely, PNR&D has found that CD4 T cells, the master control cells of the immune system, begin to disappear from the blood during ALS and that this disappearance correlates with rapid disease progression. Previous studies in mice have found that removing these cells dramatically accelerates the rate of disease. Dr. Murdock’s research therefore attempts to slow disease progression by interfering with natural killer cell function or by enhancing CD4 T cells.
Dr. Murdock’s research has gained national attention and recognition in recent years. He has been funded by multiple agencies including the CReATe Consortium and Target ALS, and he is a co-investigator with Dr. Eva Feldman on a National Institutes of Health R21 grant examining the role of NK cells in ALS. He has also been an invited speaker at conferences and institutions in Cambridge, Miami, Chicago, Toronto, and Michigan. His findings have resulted in preclinical ALS trials utilizing immune-modulating pharmaceuticals. Should the preclinical trials be successful, these drugs will be tested in Phase II clinical trials in ALS patients.
Dr. Murdock received his Ph.D. in immunology from the University of Michigan in 2010. He subsequently joined the University of Michigan Division of Pulmonary and Critical Care Medicine to examine the role of the immune system in promoting and preventing chronic pulmonary lung infections. He joined the University of Michigan Department of Neurology in 2014 to examine immune mechanisms underlying neurodegeneration, particularly ALS.
