21st-century American scientists

Gordon Murray Shepherd (21 July 1933 – 9 June 2022) was an American neuroscientist who carried out basic experimental and computational research on how neurons are organized into microcircuits to carry out the functional operations of the nervous system. Using the olfactory system as a model that spans multiple levels of space, time and disciplines, his studies ranged from molecular to behavioral, recognized by an annual lecture at Yale University on "integrative neuroscience". At the time of his death, he was professor of neuroscience emeritus at the Yale School of Medicine. He graduated from Iowa State University with a BA, Harvard Medical School with an MD, and the University of Oxford with a DPhill.

Anthony Atala (born July 14, 1958) is an American
bioengineer, urologist, and pediatric surgeon. He is the W.H. Boyce professor of urology, the founding director of the Wake Forest Institute for Regenerative Medicine, and the chair of the Department of Urology at Wake Forest School of Medicine in North Carolina. His work focuses on the science of regenerative medicine: "a practice that aims to refurbish diseased or damaged tissue using the body's own healthy cells".Dr. Atala is the creator of the first 3D bioprinters (Integrated Tissue and Organ Printing System or ITOP) and is one of the foremost leading figures in the field of organ printing. Atala and his team developed the first lab-grown organ (a bladder) to be implanted into a human. He is also developing experimental technology that can 3D print human tissue on demand.As director of the Wake Forest Institute for Regenerative Medicine, Dr. Atala leads a team of more than 400 researchers dedicated to developing cell therapies and engineering replacement tissues and organs for more than 40 different areas of the body.Dr. Atala is editor of 3 journals and 25 books including Principles of Regenerative Medicine, Foundations of Regenerative Medicine, Methods of Tissue Engineering and Minimally Invasive Urology. He has published over 800 journal articles and has received more than 250 national and international patents. Fifteen technology applications developed in Dr. Atala's laboratory have been used clinically.He serves on the editorial board of the scientific journal Rejuvenation Research, on the national board of advisors for High Point University and on the SENS Research Foundation's research advisory board. He is a founding member of the Tissue Engineering and Regenerative Medicine International Society (TERMIS) from which he received the Lifetime Achievement Award. Atala is the director of the Armed Forces Institute of Regenerative Medicine, a federally funded institute created to apply regenerative medicine.

Helen Matusevich Oujesky (August 14, 1930 – February 1, 2010) was an American professor of microbiology at the University of Texas, San Antonio. In this capacity she actively pursued environmental research on pollution of soil and water, particularly of toxic wastes.In her career span of 45 years in the field of education and research, Oujesky was the recipient of several awards such as from the National Science Foundation, Student Science Training Programs for High School Students, Minority Research Programs for Minority High School Students, and an Intervention Model Program for Girls Using Laboratory Activities in Science, Math and Engineering. On 30 January 1997, her name was incorporated in the Texas Women's Hall of Fame.
