LAB DIRECTORS

 

Andrew Dorfmann, MS, is the Director of the Embryology Laboratory and former director of the Prenatal Cytogenetics Laboratory. He received his M.S. from George Washington University in Reproductive Genetics in 1985 and is a co-founder of the Genetics & IVF Institute. He has over 20 years of experience in Prenatal Cytogenetics and Assisted Reproductive Technologies.

Mr. Dorfmann was responsible for the initiation of several of the core labs and technologies at GIVF, including the embryology lab, the andrology lab, the cytogenetics labs, and the immunoassay lab. Early in the history of GIVF, he developed rapid turn around procedures for both Amniotic Fluid cell and Chorionic Villus cell cytogenetics. Later, he implemented several new embryologic methods, such as ICSI, embryo biopsy, blastocyst transfer, and played an important role in the introduction of FISH to the Cytogenetics and Preimplantation Genetics labs. He has had numerous peer reviewed publications as well as presentations at national and international meetings in the fields of Prenatal Cytogenetics and Assisted Reproduction.

In addition to his role as a clinical scientist, Mr. Dorfmann has developed, written and implemented several large database systems now in use at the Fairfax facility. Currently he is a key member of the team working on the implementation of an electronic medical record and received a second Masters Degree in Information Systems in 2005. Mr. Dorfmann is also a member of the GIVF China Working Group and has played an instrumental role in developing, designing, opening, and managing our affiliate centers in China. Mr. Dorfmann has been with GIVF since 1984.

David Karabinus, PhD, HCLD is the Andrology Laboratory Director. Before coming to GIVF, he started his academic career with a BS and MS from Ohio State University. He went on to receive a PhD with an emphasis in Male Reproductive Physiology from Virginia Polytechnic Institute in 1988. As a post-doctoral fellow at South Dakota State University he studied the genetic structure of sperm.

In 1992, he became the Director of the Andrology Laboratory at the University of Arizona College of Medicine, a position he held for more than 10 years. In 1997, he added responsibilities becoming the Director of the Hormone Assay Laboratory and the Chair of the OB/GYN Department Human Subjects Committee. Dr. Karabinus has published extensively on sperm structure and function. Dr. Karabinus has been with GIVF since 2002.

Brian Mariani, PhD is the Chief Scientist of the Genetics & IVF Institute. His research, completed at Stanford University in the Department of Biological Sciences, focused on cancer genetics; specifically the molecular mechanism of chemotherapeutic resistance.

Following his PhD, Dr. Mariani received a Jane Coffin Childs Fellowship to study molecular genetics at Harvard University in the Department of Cellular and Development Biology. This work focused on gene structure and how the expression of genetic information is regulated during development and cellular differentiation. Dr. Mariani then served on the faculty of the Jefferson Medical College of Thomas Jefferson University, having joint appointments in the Departments of Biochemistry & Molecular Biology, and Orthopaedic Surgery. His research at Jefferson involved the molecular basis of vertebrate embryogenesis, particularly the genetic control of skeletal development. Additional studies involved pioneering work in the molecular diagnosis of clinical infectious diseases.

Dr. Mariani joined the GIVF in 1998 and established the Molecular Infectious Disease Laboratory. With his background in molecular genetics and assay development, Dr. Mariani is also Co-Director of the Preimplantation Genetic Diagnosis Laboratory. In this context, he is working on the application of genomic technology for the improved detection of genetic disease and chromosomal abnormalities in IVF generated embryos.

Michelle Ottey, PhD, HCLD is the Director of Operations for Fairfax Cryobank and Cryogenic Laboratories, Inc. She received her BA in Biology from Rosemont College in 1997. Dr. Ottey received her PhD in Genetics from Thomas Jefferson University in Philadelphia in 2003. During her graduate work her focus was on the FHIT gene, a human tumor suppressor found to be aberrant in multiple cancers. Her work led to the development of an assay by which to measure clonal survivability after exposure to UV irradiation. This assay was used to study the effect irradiation on Fhit homozygous, heterozygous, and null primary and established cells lines. The data retrieved from this assay led to work on the role of the Fhit gene in cell cycle survival pathways.

She then moved on to the University of Pennsylvania's School of Veterinary Medicine where she completed a post-doctoral fellowship during which she studied the Mob1/Dbf2 protein complex and its role in regulating chromosomal passenger proteins. This work established that Mob1 is essential for maintaining the localization of the Aurora, INCENP, and Survivin chromosomal passenger proteins on the anaphase spindle as well as a role in the dissociation of the proteins from the kinetochore region. This work was important in establishing kinetochores as sites for Mitotic Exit Network (MEN) signaling.

Dr. Ottey was interested in moving from research science to science management and thus joined Fairfax Cryobank in June 2006 at the Philadelphia site as lab supervisor. She now manages each of the Cryobanks' laboratories and is involved in other GIVF pursuits.
