IDP-Biophysics Graduate ProgramAbout the Biophysics Graduate Program


The Biophysics Graduate Program features two primary areas of research: Magnetic Resonance Imaging and Molecular Biophysics. Our program is designed to assist young scientists in developing the research skills they need to thrive in academic and clinical settings. Our program offers an informal atmosphere where students are able to work closely with faculty members, as well as other graduate students and postdoctoral fellows.

Magnetic Resonance Imaging


The Magnetic Resonance Imaging track places particular emphasis on magnetic resonance imaging (MRI). A particularly active area of research is functional MRI (fMRI) of the human brain (e.g., neuroscience, contrast mechanisms, technical development), which  is the measurement of the indirect consequences of locally increased neural activity—increased blood flow and increased blood oxygenation, both confined to the region near the neural activation. Our fMRI program emphasizes the following:

  • The development and application of faster imaging methods, with a principal application of mapping human brain function (fMRI);
  • The quantitation of clinically relevant imaging parameters such as differential relaxation times in cancerous and normal brain tissues, which can aid in the diagnosis of cancerous tissue; and
  • The development of more rigorous mathematical and statistical techniques for modeling and analyzing MRI and fMRI experiments. Fourier image reconstruction and computing of statistical activations are integral parts of MRI/fMRI.

Research also focuses on the basic physics and mechanisms of MRI. Designing improved hardware, experimental protocols and post-processing algorithms is key to achieving the goals of this program.

Research directions that stem from these goals include:

  • Creating new, faster imaging techniques and hardware
  • Understanding the precise interaction between basic neural events, their physiological consequences (e.g., blood oxygenation changes) and the nuclear magnetic resonance (NMR) signal
  • Developing new mathematical and statistical models for Fourier image reconstruction and the precise quantification of activations in structure-function relationships

Instrumentation for fMRI research is maintained by the Center for Imaging Research

Students interested in fMRI research are encouraged to apply directly to the Biophysics Graduate Program or enter our program through the Neuroscience Doctoral Program (NDP)

Molecular Biophysics


The Molecular Biophysics track encompasses the investigation, detection and use of free radicals and paramagnetic metal ions in biological systems using electron paramagnetic resonance (EPR) spectroscopy.

  • Free radicals are an integral part of cellular communication and are also involved in many disease processes (e.g., atherosclerosis and Lou Gehrig's disease).
  • Stable free radicals can be introduced at any site in a protein or peptide by a technique known as site-directed spin labeling. Free radicals are excellent reporters of their environment and, therefore, can be used to investigate protein structure and functional dynamics.
  • Paramagnetic metal ions are central to most biological processes and electron transfer systems.

Research in the Department of Biophysics focuses on:

  • The study of nitric oxide, a free radical involved in the control of blood pressure, memory and inflammation
  • Understanding the role of oxidants and antioxidants in signal transduction and apoptosis
  • Site-directed spin-labeling studies of bacterial toxins, mammalian receptors, essential bacterial transport proteins and other biomedically relevant proteins, peptides and lipid membranes 
  • Investigating the function of biological membranes and the effects of cholesterol, macular carotenoids and integral membrane proteins on their properties
  • Biomedically important metal-ion-containing proteins such as superoxide dismutase, a free-radical-scavenging enzyme that contains an active-site copper
  • The development of advanced EPR instrumentation and new EPR methodologies

The Department of Biophysics houses the National Biomedical EPR Center, one of the few national centers for EPR-related research, as well as the Free Radical Research Center and the Redox Biology Center.

Students interested in the biomedical application of EPR spectroscopy to the study of biology, biochemistry and structural biology should enter our program through the Interdisciplinary Program (IDP) in Biomedical Sciences. Students with more of a physical background who are interested in specializing in EPR instrumentation development should apply directly to the Biophysics Graduate Program.

Zachary BoydZachary Boyd

Mentor: Eric Paulson, PhD
Year Entered MCW: 2017
Previous Education: Milwaukee School of Engineering (Milwaukee, WI)​, BS, Biomedical Engineering (2017)
Research Interest: My primary area of research interest is developing a method to provide biologically adaptive radiation therapy for oncology patients, based on quantitative imaging techniques. The ultimate goal of this research is to provide a more personalized and responsive treatment for oncology patients based on reproducible, quantitative data.

Ethan DuwellEthan Duwell
Mentor: Edgar DeYoe, PhD
Year Entered MCW: 2015
Previous Education: St. Olaf College (Northfield, MN), BA, Chemistry and Philosophy (2013)
Research Interest: My research interests include visual attention, conscious awareness, and conscious experience. I am currently pursuing these interests in the DeYoe lab, where we study visual attention both behaviorally and neurophysiologically via functional magnetic resonance imaging (fMRI). The DeYoe lab develops novel fMRI paradigms to map brain patterns of attention-related activity and then uses mathematical models to explore the effects of attention on visual processing and other behaviors. The overall goal is to understand the brain mechanisms responsible for visual perception, attention, and awareness, ultimately providing tools for diagnosis and treatment of brain-related vision and attention deficits.

Alex HelfandAlex Helfand
Mentor: Jeffrey Binder, MD
Year Entered MCW: 2016
Previous Education: Boston University (Boston, MA), BA, Psychology (2012); MS, Medical Science (2014)
Research Interest: I am interested in the neural networks that mediate behavior, especially the processing of external stimuli in order to plan and execute a response. I am particularly interested in the neural networks mediating motivated behaviors and reward valuation. I am also interested in studying the biological bases for human communication (verbal and written).

 Samantha KohnSamantha Kohn
Mentor: Jimmy Feix, PhD
Year Entered MCW: 2014
Previous Education: Carroll University (Waukesha, WI), BS, Chemistry (2013)
Research Interest: The Feix lab focuses on the structure, conformational dynamics, and membrane interactions of ExoU, a key virulence factor of Pseudomonas aeruginosa that is strongly correlated with a poor clinical outcome. ExoU is a 74 kDa phospholipase that requires noncovalent interaction with ubiquitin for activity. Membrane binding of ExoU is enhanced by the phospholipid inositol-(4,5)-bisphosphate; however, the liposome binding mechanism, the liposome binding domain(s), and the role of ubiquitin in liposome binding remain unknown.  We are investigating these molecular processes using a combination of biochemical and biophysical methods.

Research Interest: My research interests involve structural imaging in brain cancer. I actively work in radiomics, a field of study dedicated to extracting quantitative imaging features from a medical image to produce a mineable database of radiological features with clinical relevance. Radiomic features are hypothesized to capture phenotypic differences within a tumor and have prognostic power. Through the combination of magnetic resonance imaging and ex vivo histology, cellular and genetic information regarding the patients tumor can be linked to macroscopic in vivo images.

Zhan XuZhan Xu
Mentor: Shi-Jiang Li, PhD
Year Entered MCW: 2012
Previous Education: Beijing Jiaotong University (Beijing, China), BS, Biomedical Engineering (2007)
Research Interest: My research focuses on improving the BOLD (blood-oxygen-level dependent) contrast in the fMRI application, as well as on improving the repeatability of the fMRI signal. To improve the contrast-to-noise ratio and repeatability, the most accepted approach is to increase acquisition duration. However, this method is not efficient enough, and motion artifacts usually become more severe during longer periods of data acquisition. As such, I am developing a new method, named the spatial compensated intro-shot turbo keyhole (SCITH) method. This multi-echo imaging technique aims to improve contrast within the same scan duration as is used in the current fMRI acquisition approach. The SCITH method is developed first at the 3T platform, but it can easily be transferred to the 7T platform. The conventional multi-echo approach is hard to implement due to the fast T2* decay at a strong magnetic field of 7T, but the SCITH method is capable of reducing the echo time interval between echoes as low as 6 ms that break the readout time limitation.

Magnetic Resonance Imaging (fMRI)


In the Magnetic Resonance Imaging track, students will take the following core courses in the first two years of entering the program:

  • Functional MRI Contrast Mechanisms and Applications
  • Functional MRI Journal Club
  • Nuclear Magnetic Resonance
  • Seminar

During a student's first two years, courses in biophysics, biostatistics and a biomedical science are taken in combination to complement the student's strengths and interests and as needed for their research direction. This allows students to gain experience in both technical and applied areas. Since students' time is not occupied by teaching requirements, they will be involved with a research area under the direction of a faculty member. Students typically coauthor several refereed journal publications prior to graduation. Directed studies and research courses are available to students, as are classes at two area universities: Marquette University and University of Wisconsin-Milwaukee.

A written comprehensive qualifying exam and oral dissertation proposal defense are expected to be completed by the middle of the third year of the program. A final dissertation defense is expected to occur by the fifth year of study.

Molecular Biophysics


In the Molecular Biophysics track, students will take the following courses in the first two years of entering the program:

  • Advanced Protein Chemistry or Free Radicals in Biology
  • Biochemistry of the Cell
  • Biophysical Techniques in Biochemistry
  • Cell Signaling
  • Electron Paramagnetic Resonance Spectroscopy (Theory and Practical Applications)
  • EPR Journal Club
  • Genetics
  • Molecular and Cellular Biology
  • Seminar
  • Techniques in Molecular and Cellular Biology

In addition to the introductory core classes listed above, students have the opportunity to take more advanced classes specific to their chosen area of research. A qualifying exam and dissertation proposal defense are expected to be completed by the middle of the third year of the program. A final dissertation defense is expected to occur by the fifth year of study.

Program Admission Requirements

The Biophysics Graduate Program encourages applications from students with strong backgrounds in chemistry, biology, biochemistry, biomedical engineering, physics or mathematics and an enthusiasm for carrying out scientific research. The program consists of two major and largely independent tracks—Magnetic Resonance Imaging and Molecular Biophysics.

Those interested in pursuing the Magnetic Resonance Imaging track should apply either directly to the Biophysics Graduate Program, the Neuroscience Doctoral Program (NDP), or to the Medical Scientist Training Program (MD/PhD). Applicants to this track are expected to have a high level of competence in physics and mathematics. However, the program has also admitted students with backgrounds in biology, psychology and medicine.

Students interested in Molecular Biophysics should pursue admission through the Interdisciplinary Program in Biomedical Sciences (IDP) or the Medical Scientist Training Program (MD/PhD). The faculty in this section use biophysical techniques to study structural biology, free radicals in biology and paramagnetic metal ions in biological systems. For example, current research includes studies on protein structure, functional dynamics and free radical spin trapping.

A Bachelor’s degree (either completed or in the process of completing) is required for admission to any MCW graduate program. Applicants will ideally have a 3.0 or higher grade point average (GPA), as well as quantitative and verbal reasoning GRE scores at or above the 50th percentile (3.5 or higher writing score). Personal statements and letters of recommendation from professors, advisors, research supervisors, etc. who know you well are highly regarded in the admission process. Prior research experience is also strongly considered.

The MCW Graduate School operates on a rolling admissions basis. However, applications accepted by the priority application deadline of January 15th will receive first priority for admission the following Fall. Students are admitted once per year.
