Committee on Molecular Metabolism and Nutrition Curriculum

Molecular Metabolism and Nutrition

The Metabolism Program at the University of Chicago embodies a unique structure that takes full advantage of the strengths and character of the University of Chicago.  The Committee on Molecular Metabolism and Nutrition is an interdepartmental, degree-granting body that draws its faculty from the ranks of basic science and clinical science.  This is possible because all these disciplines share the same campus and often the same building. This provides the student with the opportunity to acquire sound basic training in biochemistry.  At the same time, this training is tempered by constant exposure to the impact of metabolism on human health and well being. This provides integrated training in the basic biochemical mechanisms through which foods and nutrients interact to optimize health, the pathological consequences of malnutrition, and the interplay of nutrition and human behavior.

The Biomedical Sciences Cluster

The Committee on Molecular Metabolism and Nutrition is integrated within a cluster of graduate programs from the Committee on Cancer Biology, the Committee on Immunology, the Committee on Microbiology, and the Department of Pathology Molecular Pathogenesis and Molecular Medicine program. The five academic units share a joint Admissions Committee, several common courses, a seminar series, and additional common events for students and faculty within the cluster. The goal of the cluster system is to encourage interdisciplinary interactions among both trainees and faculty, and to allow students flexibility in designing their particular course of study.  

In addition, students have extensive opportunities for interaction with the three other clusters within the Biological Sciences Division: the Molecular Biosciences Cluster; the Darwinian Sciences Cluster; and the Neurobiology Cluster.  These clusters offer courses and sponsor seminars and symposia open to Metabolism students.

Program Philosophy

The philosophy of the program is to provide students with a wide range of educational opportunities in a research-rich environment that will stimulate the student to engage in the life-long pursuit of knowledge through self-learning.  Didactic courses during the first year provide education in the principles of basic science.  In the summer and continuing into the second year, coursework gives way to interactive training that stresses the evaluation of literature, effective communication, and hypothesis testing combined with early exposure to research.  This is enriched by a strong seminar program that exposes the student to the national leaders in metabolism research and policy.

Prerequisites

  • * A minimum of one year of college chemistry, including organic chemistry.
    * One year of college physics and a background in calculus.
    * A minimum of 4 semester or 5 quarter courses in the biological sciences, including biochemistry. Accompanying laboratory courses are strongly recommended.
  • * One course in statistics, including computer-based analysis.

Formal Coursework

A minimum of 9.5 didactic courses are to be selected from 7.5 required courses plus electives.  It is required that students maintain a minimum overall “B” average in their coursework.  Any Cs must be offset by As to maintain a B average and a grade of B or better must be achieved in all programmatic courses.

The Programmatic Core in Metabolism (4.5 credits)

  • Molecular Nutrition 1 (MOMN 36500).  Students are exposed to a comprehensive review of nutritional physiology and requirements, including the regulated digestion, synthesis and/or metabolism of vitamins, minerals, lipids, proteins and carbohydrates.  Various lecturers specialized in specific areas of metabolic research participate throughout the quarter.  The course culminates with the students writing a comprehensive paper linking several of the topics covered throughout the quarter.  Brady and Staff.  Autumn.

    Molecular Nutrition 2 (MOMN 36600).  This course is an extension of Molecular Nutrition 1 and investigates the physiological control of systemic metabolism.  Heavy emphasis is placed on the coordinate regulation of glucose and lipid metabolism by skeletal muscle, liver, adipose tissue, pancreas and brain.  The format of the course is a combination of lectures and student presentations of primary literature.  At the end of the course, students are expected to write a grant application to investigate a current area of metabolism research and then present and defend the proposal to the lecturers and students.  Reardon and Staff.  Winter. 
  • Grant Writing (MOMN 30910).   Students will gain extensive exposure to the grant writing and review processes.  Several speakers will lecture on the various funding agencies, types of grants, and general approaches to grant writing.  Students will read funded applications from CMMN faculty to learn the proper approaches for successful grant writing, including responding to reviewers’ critiques.  Students will be expected to complete a 20-25 page R01 style grant application by the end of the quarter, which will fulfill the mock grant proposal requirement for the CMMN students.  The course culminates with a mock grant review panel in which the students read and critique each other’s applications. Brady.  (This course will be held Winter 2015).

    New Insights into Metabolic Research (MOMN 40400).  This course is conducted as a seminar series.  Students will broaden their exposure to metabolism related research through bi-weekly faculty and student presentations of research data and primary literature.  Additionally, prominent researchers from other institutions are invited to give a seminar and meet alone with the students to discuss their career paths, experiences in running successfully funded labs and use of cutting edge experimental approaches. Attendance is mandatory for first and second year students but all students are strongly to attend.  Rhodes.  Autumn, Winter, Spring, Summer.

Reading and Laboratory Rotations

  • . Directed Independent Research - MOMN 30100 (Winter)
    . Directed Independent Research - MOMN 30100 (Spring)

In the Winter and Spring of their first year, students are required to perform 10-week, graded rotations through laboratories of interest.  Since the student will choose their thesis lab during these rotations, it is critical that serious thought and effort (reading papers, talking to the PI and lab members, etc.) be given before choosing the labs.   Students should contact prospective laboratories in the preceding quarter to ensure that space/resources are available.  In the following quarter, students will present an overview of their project and results from their rotation.  A third, optional rotation can be performed during the summer quarter. It is expected that a student will have chosen their thesis research lab no later than the end of their first year.

Current Topics in Nutritional Research (0.5 credit)

The Committee holds a seminar series/journal club biweekly throughout the year.   Student attendance and participation are required Autumn, Winter and Spring quarters of their first two years.  At the end of the second year, students will be graded pass/fail. Continued student participation in this series is expected until graduation.

In the Autumn, CMMN faculty members will give research talks to further expose students to research being conducted by Committee members.  In the Winter through Summer quarters, faculty presentations will either comprise research talks or presentation of a high profile, recent journal article related to Metabolism research.  Additionally, prominent outside speakers will be invited periodically to give research seminars, and students will meet with the speaker immediately after the talk.

Students are also required to present twice yearly.  In the first year, presentations will be based on the laboratory rotation performed the previous quarter.   Second year students will present a mock grant proposal in the winter (see below) and a journal article in the Spring.  In subsequent years, students are required to present on their thesis research project once a year.  The second presentation can either be discussion of a journal article, or for more advanced students, a second presentation of their own research.

Student Teaching

Students are required to teach as part of their doctoral training.  This requirement may be met by assistant teaching two courses that meet the Divisional requirement for a full TA-ship or taking the Divisional TA training course and assistant teaching one course.  The TA requirement should be completed by the third year of residence.  Teaching performance is evaluated by the course director and filed in the Graduate Affairs Office.

Mock Grant Proposal

In the Winter of the second year, students are required to complete a mock grant proposal, consisting of a 10 page, NIH-style grant proposal and a 45-minute oral presentation.  The proposal should define an unaddressed research area in Molecular Metabolism and Nutritional Biology, propose 2-3 specific aims to explore the problem and describe experiments that would be conducted over a 5-year period.  Previous proposals will be available to be used as templates.  The topic chosen cannot be directly related to the student’s thesis research and must be approved by the CMMN Chair.  The student will present and defend their mock grant proposal to the Metabolismn Committee faculty and students.  A committee comprising of three CMMN faculty members chosen by the CMMN Chair will evaluate each mock grant proposal and oral presentation.  The student will meet privately with the committee members after the oral presentation to discuss the proposal and to answer questions.  Any deficiencies in the written proposal, oral presentation and/or background knowledge of the research area will have to be addressed before the student is passed.  All required revisions must be completed by the end of the following quarter.

Thesis Requirements

Starting in the Summer/Autumn after the second year, a student should begin in earnest, research work towards their thesis project.  By Autumn of the third year, the student should form their thesis committee and submit their thesis proposal.

The thesis committee will comprise of four members: the student’s advisor, a committee chair (not to be the advisor) and two other members of the Metabolism Committee. The thesis proposal should consist of a detailed background of the research area to be studied, preliminary data demonstrating the feasibility of the proposed experiments, 2-3 specific aims and a supporting experimental plan to address the research area.  Total length should be approximately 20 pages. The proposal should be given to committee members at least two weeks before the oral defense of the thesis proposal. The student will make a public presentation to students and faculty of CMMN, and then meet with their committee in private to answer questions and discuss the proposed experiments in detail.  Once accepted by the committee, the student will then formally enter the Ph.D. program.

Thesis

Each student will be required to complete a dissertation documenting original research within 6 years of the thesis proposal defense.  However, it is expected that students will complete their thesis during their fifth year in the program.   The thesis should consist of 2-3 chapters, and it is expected that at least two of these chapters will result in first author publications in prominent journals.  Students failing to meet these time limits must apply for readmission to the Ph.D. program.
