Simon J. Rhodes Ph.D. Dean of the IUPUI School of Science

Simon J. Rhodes, Ph.D.

Dean, School of Science
Professor, Department of Biology
Biology Department

I am proud to serve as the Dean of Science. In the IUPUI tradition of collaboration, the IUPUI School of Science delivers undergraduate and graduate degrees from both Indiana and Purdue Universities, including ten independent Ph.D. programs. Our motto is that "We Graduate Success Stories" and in this web site you will find many examples of student success from our undergraduate and graduate programs. You will also find descriptions of the success of our faculty and staff in achieving the best in teaching and research.

The School of Science educates students from all over the world in a dynamic and diverse leaning environment. We are particularly proud to serve the State of Indiana by putting record numbers of STEM graduates into the Indiana economy thereby improving the success of businesses and services in the State.

IUPUI Science students take advantage of a learning environment that is unequaled in the Midwest

IUPUI is a beautiful campus in the city of Indianapolis located next to city government, museums, libraries, canals, and parks. Global pharmaceutical, IT, biotech, engineering, financial and insurance companies are within walking distance. The campus is the largest biomedical research center in the State and is home to the Indiana University Schools of Medicine, Dentistry, Nursing, Rehabilitation Science, Public Health, Social Work, etc. Five major hospitals are located on or connected to the campus by monorail train. In this environment, Science students have outstanding opportunities to do career-relevant research, shadowing and internship experiences relevant to all of our degree programs, both throughout the academic year and in the summer.

As early as freshman year, students in the School can engage in research and internships with faculty mentors in the school and across campus and the city. Through these experiences our students learn research skills and problem solving; they learn to work in teams; they learn how to effectively communicate; they travel to conferences to present their work; they earn authorship on publications; and they develop contact networks that serve them for a lifetime. Coupled with an outstanding academic experience, this environment prepares our students for their next step in the workplace, in graduate school, in professional school, or in other chosen pathways.

IUPUI is a national leader in developing new methods of teaching STEM subjects

We engage and excite students, while holding them to high standards and stressing critical and analytical thinking. Our students learn in exciting, discovery-based classes.

IUPUI Science students learn through leadership. As peer mentors, advisors and tutors, our students are partners in education and contribute to each other's success.

IUPUI Science students enjoy outstanding resources that support their success

We provide dedicated advisors for each program, learning resources such as the Mathematics Assistance Center (the "MAC"), the Biology Resource Center, the Physics Learning Space, etc. The School of Science Office of Pre-Professional and Career Preparation (PREPs) engages our undergraduate and graduate students and alumni in academic and career planning to help translate their professional goals into reality.

IUPUI Science faculty perform world class research

In partnership with our undergraduate students, our graduate students, and our staff, Science faculty do federally-funded research that is important for Indiana, the USA, and the world. Their research improves our economy, our health, and our quality of life. Through the success of our research efforts, in partnership with the IUPUI School of Engineering & Technology, we have recently completed a new research and teaching building that was completed with using any Indiana tax payer funds. And we are not done yet!

Courses Taught / Teaching

I am also a professor of Biology in the School. In the fall, I teach BIOL-K488 "Endocrinology in Health and Disease" (3 credits) which is an introduction to human endocrinology, including the biology of the endocrine organs and the hormones that they release. The course examines both normal endocrine function and the common diseases involving hormone physiology. In addition, in this course students learn how endocrinology impacts everyday life. 



Our research program investigates the pathways that control pituitary gland organogenesis. Through collaborations with pediatric endocrinologists, we have translated this work to the clinic, defining new forms of combined pediatric hormone deficiency diseases and developing new diagnostic and genetic counseling tools. The anterior pituitary gland secretes polypeptide hormones that are essential for human development and physiology parameters including growth, reproduction, the stress response, metabolic homeostasis, and lactation.

Diseases involving pituitary dysfunction therefore can involve severe syndromes affecting many tissues and systems.

During embryogenesis, the actions of transcription factors, such as the LHX3 and LHX4 homeodomain proteins, govern the establishment of the hormone-secreting pituitary cell types. Through established collaborations with clinical partners, our laboratory has demonstrated that mutations in the LHX3 and LHX4 genes cause severe pediatric combined pituitary hormone deficiency diseases and other symptoms such as nervous system defects.

For example, through biochemical structure/function analyses and characterization of patient phenotypes, we have determined that mutations affecting distinct parts of the LHX3 protein are correlated with specific disease outcomes: mutations only compromising the carboxyl terminus are associated with a more restricted disease involving pituitary hormone deficiency but not nervous system problems. We have generated a novel knock-in mouse model of a unique form of pediatric hormone deficiency disease that we recently described.

The resulting mice display marked dwarfism, thyroid disease, female infertility, and reduced male fertility. Our work has been funded by the NICHD/NIH, the NSF, and the USDA.
