Hanne M Hoffmann, PhD

 Hanne Hoffmann

  • Ph.D.         12/2010 Neuroscience, Montpellier University 2, France, European mention
  • Ph.D.         12/2010 Biochemistry, Autonomous University of Barcelona, Spain, Cum Laude
  • Postdoc     06/2011-04/2016 Department of Reproductive Medicine, UC San Diego

Dr. Hoffmann received her BS (2005) and MS (2007) from Montpellier University II (France), and her PhDs in Biochemistry from the Autonomous University in Barcelona (Spain) and in Neuroscience from Montpellier University II (France) in 2010. During her graduate work Dr. Hoffmann’s research was focused on understanding how cocaine addiction impacted GPCR heterodimer interaction and signalling in the brain. In 2011 Dr. Hoffmann joined the lab of Dr. Pamela Mellon at UC San Diego for her postdoctoral work in reproductive endocrinology. At UC San Diego, Dr. Hoffmann studied the role of homeodomain transcription factors in GnRH neuron development and fertility.

In 2018 Dr. Hoffmann joined the faculty in Animal Science at Michigan State University. Dr. Hoffmann’s current research interests are at the intersection of behavioral neuroendocrinology and reproduction. By using transgenic mouse models, Dr. Hoffmann’s research focuses on understanding how light and seasonal changes in day length impacts hypothalamic network function, and its control of reproduction and labor progression.

In recognition of her contribution to the field of neuroendocrinology, reproductive function and pregnancy, Dr. Hoffmann has received numerous awards, including the Neena Schwartz Young Investigator Award in Basic Science from Women in Endocrinology (2016), the Early Investigators Award supported by Merck & Co., Inc. from the Endocrine Society (2016), the New Investigator Award from the Society for Behavioral Neuorendocrinology (2017) and the Basil O'Connor Starter Scholar Research Award from the March of Dimes (2019).

Duong received her BS and MS in Biological Sciences from Wayne State University (Detroit, MI). She has expertise in microbiology, computational biology, molecular evolution and comparative genomics. Her research was focused on sequence comparison using next-generation sequencing data to address the process and the dynamic of mutations such as SNPs and Indels in coding and noncoding regions. In the Hoffmann lab, Duong is interested in applying sequencing data analysis to understand how light and seasonal changes affect gene expression level which in turn impacts the signalling in the brain and the reproductive function. Using mice as a model, it is also important to understand the similarities and differences between mice and other animals especially human.


Alexandra Yaw, PhD Neuroscience

Postdoc June 2019-current

A_Yaw Headshot

Dr. Alexandra Yaw graduated from Albion College in 2014 with a B.A. in Psychology and minors in Cell and Molecular Biology and Chemistry. In 2019, she completed her Ph.D. in Neuroscience from Kent State University in the Department of Biomedical Sciences. Throughout her career, her research interests have been focused on the complex relationships guiding biological rhythms and behavior. At Albion College, Alexandra completed a Departmental Honors Thesis focused on the relationships between sleep, nutrition, and athletic performance. Her dissertation research focused on the generational effects of paternal cocaine abuse on offspring behavior and underlying neurochemistry, with a specific focus on circadian and social behaviors. In the Hoffmann Lab, Alexandra’s current projects focus on light and the rhythmic control of reproductive function.

Dana and Hanne

Dana has a degree in nursing, and a PhD in biomedical research. Dana did her postdoc at UC San Diego where she primary focused on pituitary function. After her PhD she worked in biotech for a number of years before combining her skills in research and nursing, allowing her to develop and manage clinical trials.

Duong, Thu V-1

Thu Duong is a fourth year DO-PhD student in the department of Biochemistry and Molecular Biology. She received her BS in Biology from Truman State University, Missouri and just completed the first two years of medical school at the College of Osteopathic Medicine. Thu is excited to be back in the lab. Her project in the Hoffmann lab is about the melatonin receptors and how they affect uterine contractions, and she will be working with both human tissues and mouse tissues. She also hopes to expand her knowledge in bioinformatics by learning how to analyze published sequencing data sets. Thu is passionate about prenatal care, especially how to improve pregnancy outcomes. She enjoys being in the Hoffmann lab and learning about circadian rhythms during pregnancy..

 Brooke Devries crop

Brooke is a Lyman Briggs student pursuing a degree in neuroscience. After her undergraduate studies, she plans on continuing her education in graduate school by pursing a Ph.D. in neuroscience. She plans to conduct research on affective disorders. Brooke is interested in the Hoffmann lab because, after living in Michigan her whole life, she can see that exposure to light changes people in many ways and is excited to learn more.

In her free time, Brooke enjoys reading, both fiction and scientific works.

Awards: Recipient of the Summer Research Fellowship (SRF) Award from the Endocrine Society (2019)


I am currently a Human Biology major in the Lyman Briggs College. I hope to go to medical school and work to provide underprivileged people proper medical care. I believe that it's extremely important for research to be interminable, with new discoveries always being made and ground constantly being broken. I felt that Dr. Hoffmann's lab had this component to it because so little is known about how circadian rhythms affect our physical and mental health, as well as fertility. I know that I will continuously gain knowledge and be a part of novel discoveries at Dr. Hoffmann's laboratory.

Aside from research and school work, in my free time, I love to read medical anthropology and write!


Asad Muhammed

 Asad stand up

Asad is a third year Lyman Briggs student majoring in Physiology. He is working towards becoming a physician and practicing primary care in an underserved community. He is interested in the Hoffmann Lab because he is intrigued by the role of diet in the structural and physiological development of body systems that depend on the proper function of processes at the biochemical level. Currently, Asad is researching the effects of lipid deficiency on the late stage brain development of mice embryos.

In his free time, Asad loves to read science fiction and doing martial arts.


Autumn Mclane-Svoboda

October 2019-current


 Autumn is currently a Mechanical Engineering student with a concentration in Biomedical Engineering. Once she graduates she plans to go to graduate school to get a masters or PhD in Biomedical Engineering. She hopes to have her own lab one day to help merge advancing technology with the human body and make peoples lives better. Autumn is interested in the Hoffmann Lab because it is the perfect welcoming environment to grow as a student and researcher. In her free time she enjoys reading, water skiing, and being outside.


Aneesh Sai Cherukuri

October 2019-current


Aneesh is a sophomore in the Lyman Briggs College majoring in Neuroscience. Once he graduates, he plans on working towards becoming a Neurosurgeon. Aneesh is part of the Hoffmann lab because it provides him with a wide range of technical utility that is hard to find elsewhere on this campus. Currently, Aneesh is working in the subdivision of chronopharmacology and plans to develop a more specific study in the future. In his free time, he loves to dance and read!
