2016 - Eva Feldman

Amyotrophic lateral sclerosis (ALS) is a devastating neurodegenerative disorder in which the loss of large nerve cells in the brain and spinal cord produces progressive weakness and eventually death. In the decades since the approval of riluzole, the only FDA approved medication to moderately slow progression of ALS by 2 months, no new therapies have arisen to alter the course of the disease. Stem cells have emerged as an attractive option in treating ALS. While various stem cell types are being evaluated in preclinical and early clinical applications, we have used spinal cord neural progenitor stem cells in two FDA approved clinical trials to treat ALS. In both the Phase I and II clinical trials, ALS subjects received direct transplantation of stem cells into different areas of their spinal cord. Although these trials were primarily conducted to evaluate the safety of this approach, clinical progression was monitored and we have preliminary insight into the beneficial therapeutic role of stem cell therapy in ALS disease progression. Overall, results demonstrate that intrinal transplantation of stem cells in ALS patients is feasible and well-tolerated and the therapeutic signal warrants another larger FDA trial which will begin in 2016. This marks a new era for stem cell therapy and for our treatment of ALS.

2015 - Trachette Jackson

Mathematical biology, the mathematical modeling of phenomena in the biomedical sciences, is one of the fastest growing areas in applied mathematics. In this introduction to the field, Trachette Jackson highlights its historical successes and showcases ways in which mathematics and high-powered computing are being used to tackle some of the biggest biological challenges facing our world today.

Jackson is an award-winning teacher scholar whose research in mathematical oncology has received international attention. In 2003, she became the second African American woman to receive the prestigious Alfred P. Sloan Research Award in Mathematics. The main focus of Dr. Jackson’s research is combining mathematical modeling, numerical simulation, and in vivo tumor vascularization experimentation to gain a deeper understanding of tumor growth and vascular structure at the molecular, cellular, and tissue levels.

2014 - George Djorgovski 

The growing capacity of computers to collect and store data has been transforming science, leading to a new era in which scientific databases are primary research tools. The virtualization of these databases gives any person who has a computer and Internet connection the opportunity to perform scientific research. This development, however, has come with a challenge: how do you analyze extremely large scientific databases and turn that data into knowledge and scientific discoveries?

S. George Djorgovski is at the forefront of this new data-intensive and computationally enabled paradigm of science. One of the founders of the Virtual Observatory concept and the emerging field of astroinformatics, he has served as chairman of the U.S. National Virtual Observatory’s science definition team. Djorgovski will discuss how big data and data virtualization are revolutionizing science and scholarship in the 21st century.

2013 - Leigh R. Hochberg

Sending emails, playing computer games, drinking coffee. These activities have been impossible for people who are “locked in” their bodies – awake and alert, but unable to move or communicate due to brainstem injuries, strokes, or illnesses like ALS. Until now. Leigh R. Hochberg and his fellow researchers are developing brain-machine interfaces that allow paralyzed people to accomplish these feats and much more.

Hochberg and his colleagues found that even though the pathways connecting the brain to the rest of the body, such as the spinal cord, have been broken, the brain can still send the signals that control movement. They developed BrainGate, a neural interface system that plugs into the brain, picks up those signals, and sends them to a computer that translates them into moving a cursor or controlling a computer keyboard or robot arm. Paralyzed people can literally move objects by thinking about them!

2012- Garrison W. Cottrell 

How does the activity in our brain create the mind? One way to understand the mind is to build computer models that “do the same things people do.” Garrison W. Cottrell investigates this question in the context of how we see: how do we recognize faces, facial expressions, and objects? This seems so simple – we look, we see! But it isn’t that simple, something you discover if you try to write a computer program that can automatically label faces and objects with their names. Prof. Cottrell will described his computer models of how we see, and how our brains can often fool us about what we see.   Cottrell, who has been working on neural network models of mental processes for over 30 years, describes the field of cognitive science and how building working models of mental processes can provide insights into how the mind works. His research group, Gary’s Unbelievable Research Unit (GURU), focuses on how the visual system might learn representations of the world, how our attention is drawn to different objects in our visual field, and how we use these processes to recognize objects.

A group of racecars piloted by the best drivers in NASCAR are turning a corner. Without warning, one of the cars suddenly hits the outside wall. There were no engine failures, no flat tires, and none of the cars touched … so what happened ? Physics professor and author of The Physics of NASCAR, Diandra Leslie-Pelecky details what it takes to make racecars faster and safer, and why driving a stock car is much harder than you might think.

The nighttime symphony of croaking frogs and toads is becoming a thing of the past and Tyrone Hayes, an internationally recognized biologist, knows why. His research on atrazine, a widely used pesticide found in groundwater, local streams, and ponds, has revealed that the product is a potent endocrine disrupter that chemically castrates and feminizes exposed male amphibians. Atrazine also causes neural damage and hyperactivity and induces a hormonal stress response that leads to retarded growth and immune suppression, resulting in increased disease and mortality rates.

Heller has made groundbreaking theoretical contributions in quantum dynamics, spectroscopy, semiclassical approximations, and condensed matter physics.  He is perhaps best known for his seminal work on the time-domain wavepacket approach to molecular spectroscopy, and on the quantum mechanics of classically chaotic systems.  More recently Heller has used his deep understanding of quantum mechanics to explain fascinating coherence effects in quantum corrals and quantum dots, as well as the beautiful "branched and fringed electron flow" in semiconductor heterostructures, discovered experimentally by Bob Westervelt's group at Harvard.

2008 - John Noble Wilford

Since joining the New York Times as a science news reporter in 1965, Wilford has committed to sharing this informed wonder with his readers. As a journalist, he has covered cutting-edge technology and scientific breakthroughs, including space exploration, but also has witnessed the tragic consequences of such endeavors, like the Challenger space shuttle explosion. Throughout his career, Wilford has gained not only an appreciation for science and technology, but a curiosity.

2005 - Dr. Robert   Devaney

Professor of mathematics at Boston University and an expert in dynamical systems theory, Dr. Devaney received the Award for Distinguished University Teaching from the Northeastern section of the Mathematical Association of America in 1994.  He produced the Mandelbrot Set Explorer, an online, interactive series of explorations designed to teach students at all levels about the mathematics behind the interesting images known as the Mandelbrot and Julia sets. In his lecture entitled "Chaos Games and Fractal Images" he described the beautiful images that arise from the “chaos game” and showed how the simple steps of this game produce the intricate images known as fractals.  He also touched on the applications of this technique used in data compression as well as in Hollywood.

2004 - Dr. Ursula   Goodenough

Dr. Ursula Goodenough is a renowned cell biologist, researcher and author who shared experiences of her travels in Tibet where she taught cell biology to exiled Tibetan monks that had no previous scientific education. Just prior to this, she had accepted an invitation to teach the Dalai Lama the principles of molecular evolution. She spoke of these experiences and how they resonated with her own deeply held beliefs about the relationship between spirituality and science. These experiences strengthened her conviction that the best way to teach science is through narrative - telling the science in story, a method she very effectively illustrated in this lecture.

2003 - Dr. Isabel Hawkins

Dr. Isabel Hawkins, Director of the Center for Science Education at the University of California, Berkley, Space Sciences Laboratory (SSL).  Through examples of education and outreach programs with which she is actively involved, she shared her research experiences which ultimately led to a better understanding of the effects of the active sun, the sun-earth connection and "space weather".

2002 - Dr. Dudley   Herschbach

Dr. Herschbach’s lecture was modeled around his reflections in teaching and learning science. He was a charismatic speaker who emphasized the critical role that individual teachers played in his education. Dr. Herschbach is renowned for his studies on energy redistribution and its exchange in chemical reactions.

2001 - Dr. Francisco J. Ayala

Dr. Ayala, a world-renowned molecular geneticist and former priest, gave a fascinating talk to reveal how teachings in both evolution and religion can exist harmoniously.  He is extremely emphatic about promoting the philosophical compatibility of scientific knowledge and methods and religious faith and has been described as the Renaissance man of evolutionary biology.
