Luis Herrera-Estrella, PhD

President's Distinguished Professor

Texas Tech University

plant genomics

Luis Rafael Herrera-Estrella is the President's Distinguished Professor of Plant Genomics and the Director for the Center for Functional Genomics of Abiotic Stress in the Department of Plant and Soil Science at Texas Tech University's College of Agricultural Sciences & Natural Resources. Dr. Herrera-Estrella came to Texas Tech in 2018 thanks to a grant from the State of Texas Governor's University Research Initiative (GURI). He leads a team in the Center that examines how plants adapt to thrive in the presence of environmental stresses such as extreme heat and cold, drought and in the presence of brackish water sources. Herrera-Estrella is known and respected worldwide for his work in cotton genomics, having earned the distinction in 2015 as one of the 100 most influential people in biotechnology by Scientific American. He previously served as the director and full professor of the National Laboratory of Genomics for Biodiversity (LANGEBIO) in Guanajuato, Mexico, where remains a professor emeritus. His research focuses on the molecular mechanisms that allow plants to cope with a continuously changing environment. In particular, he has studied the two fundamental processes of molecular responses to light as a source of energy and a developmental signal, and nutrient availability. Herrera-Estrella was able to eventually identify DNA regulatory elements that allow plants to activate genes in response to light stimuli and the protein sequence present in many corresponding gene products that ultimately allow participation in the photosynthesis process. A holder of 15 patents, Herrera-Estrella has published more than 180 research papers and 47 book chapters and other reviews while having delivered more than 200 presentations on his work. He served as a senior international research scholar at the Howard Hughes Biomedical Institute from 2012 to 2017 and earned the Dr. Luis Federico Leloir Award in 2012 from the Argentinian Ministry of Science, Technology and Innovation. Herrera-Estrella earned his doctoral and postdoctoral degrees in genetics from the State University of Ghent, Belgium.

Maria C. E. Jacobs, MD

Director, Radiation Oncology at Mercy

Mercy Medical Center

Radiation Oncology, Radiation, Oncology, Radiation Therapy, IORT

Maria C.E. Jacobs, M.D., leads the Radiation Oncology team at Mercy Medical Center in Baltimore, Maryland. She places top priority on quality patient care, medical excellence and helping her patients get the best possible radiation therapy treatment. Dr. Jacobs brings passion, enthusiasm and a heart for caring to her patients. In her role as Director of Radiation Oncology at Mercy, Dr. Jacobs oversees all radiation therapy and radiotherapy services for the hospital.

Dr. Maria Jacobs works in close collaboration with the cancer surgeons in The Breast Center at Mercy to coordinate post-surgical treatment for breast cancer patients. Intraoperative Radiotherapy (IORT) is a state-of-the-art technology that allows patients to get treated in one single radiation therapy session – a notable advantage over the many multiple visits required prior to IORT.

Patients are afforded other advantages because of the single session IORT treatment. Preservation of more healthy tissue and reduced side effects from the radiation are benefits many patients experience.

Dr. Jacobs and Dr. Neil Friedman, Medical Director at The Breast Center, were the first team of doctors in the state of Maryland to use Intraoperative Radiotherapy (IORT).

Dr. Jacobs and her team of Radiation Oncology specialists also use TrueBeam™ technology for the delivery of targeted radiation. This safe, faster, more precise cancer treatment option represents an immense leap forward in the speed and accuracy in which the radiation can be delivered. Dr. Jacobs sees this as a decided advantage for most patients. Cancer cells are attacked by an aggressive beam of radiation while minimizing the impact on surrounding tissue.

Dr. Jacobs beams with pride when she talks about the advances that have been made in radiation technology, treatment plans, and research. But like most top-rated doctors, Dr. Jacobs believes treating the patient means more than treating the disease. It’s about caring for the person…that unique, one-of-a-kind individual who has family and friends, hopes and dreams … and a life beyond cancer.

The Mercy spirit surrounds you when you’re anywhere near Dr. Jacobs. She laughs easily, hugs abundantly and shares her vast depth of knowledge with patients and their families in the most engaging way.

Dr. Gushchin is well-recognized for his experience in treating complex cancers with HIPEC (Hyperthermic Intraperitoneal Chemotherapy). Dr. Gushchin trained under the internationally renowned surgical oncologist Dr. Paul Sugarbaker to master this procedure, which involves cytoreductive surgery followed by a heated chemotherapy solution to reduce and eliminate tumors. Dr. Gushchin has participated in over 150 HIPEC surgeries and provides patients expertise in complicated HIPEC surgeries including repeat HIPEC surgeries, simultaneous liver resections at the time of HIPEC as well as other advanced surgical treatments in conjunction with HIPEC treatment.

Isolated Limb Infusion gives Dr. Gushchin a fighting chance to save his patients’ affected arms and/or legs, reduce or shrink the cancerous tumor and avoid the need for a more radical surgery.
