The Dark Side of Science: Misconduct in Biomedical Research
Jul 9 @ 11:00 am – 12:30 pm

Online Zoom Event with Dr. Elisabeth Bik

The event is a seminar-style presentation followed by a Q&A.

Science builds upon science. Even after peer-review and publication, science papers could still contain images or other data of concern. If not addressed post-publication, papers containing incorrect or even falsified data could lead to wasted time and money spent by other researchers trying to reproduce those results. Several high-profile science misconduct cases have been described, but many cases are yet undetected. Dr. Elisabeth Bik is an image forensics detective who left her paid job in industry to search for and report duplicated and manipulated images in biomedical articles. She has done a systematic scan of 20,000 papers in 40 journals and found that about 4% of these contained inappropriately duplicated images. In her talk she will present her work and show several types of inappropriately duplicated images. In addition, she will show how to report scientific papers of concern, and how journals and institutions handle such allegations.

After receiving her PhD in Microbiology at Utrecht University in The Netherlands, Elisabeth Bik worked 15 years in the lab of David Relman in the School of Medicine at Stanford on the microbiomes of humans and marine mammals. In May 2014, she founded Microbiome Digest, an almost daily compilation of scientific papers in the rapidly growing microbiome field. From 2016-2019, she worked at two microbiome startup companies, uBiome and Astarte Medical. In March 2019, she left her job to become a science integrity volunteer and occasional consultant. She can often be found discussing science papers on Twitter at @MicrobiomDigest, writing for her blog ScienceIntegrityDigest or searching the biomedical literature for inappropriately duplicated or manipulated photographic images and plagiarized text. Her work has been recently featured in Nature.

Reimagining the Nitrogen Cycle: Designing Selective Materials and Process for Wastewater Valorization
Jul 22 @ 11:00 am – 12:30 pm

Online Zoom Event

Zoom link provided to attendees the day of the event.

Reimagining liquid waste streams as resources can lead to recovery of valuable products and more efficient, less costly approaches to reducing harmful discharges to the environment. The nitrogen cycle has been drastically affected by humans via Haber Bosch fertilizer production, and results in net discharges of nitrogen that alter aquatic environments. The Tarpeh Lab develops and evaluates novel approaches to resource recovery from “waste” waters at several synergistic scales: molecular mechanisms of chemical transport and transformation; novel unit processes that increase resource efficiency; and systems-level assessments that identify optimization opportunities. We design and investigate selective separations to recover high-purity products from pollutants in wastewaters. Leveraging these molecular-scale insights can increase the sustainability of engineered processes in terms of energy, environmental impact, and cost. In this seminar, we will discuss two selective nitrogen separations: 1) ion exchange resins loaded with transition metals and 2) electrochemical nitrogen stripping. Integrating investigations of novel materials and processes can identify criteria for future materials and enable processes with unprecedented performance.
Professor William Tarpeh received his PhD from the University of California, Berkeley, in environmental engineering. He completed an MS in environmental engineering at Berkeley and a BS in chemical engineering from Stanford University. He is currently an assistant professor at Stanford University in the Department of Chemical Engineering.

Protecting Urban Surface Waters from Pesticide Related Toxicity: Science Driven Prevention and Response
Jul 29 @ 11:00 am – 12:30 pm

Aniela Burant, PhD
Senior Environmental Scientist
California Department of Pesticide Regulation

Online Zoom Event

Zoom link provided to attendees the day of the event.

The California Department of Pesticide Regulation (CDPR)’s Surface Water Protection Program (SWPP) has been monitoring pesticides in urban waterways since 2008. Pesticides are a concern in urban waterways due to high use of pesticides in urban areas and high potential for pesticide runoff from impervious surfaces. SWPP’s urban monitoring studies have found concentrations of pyrethroids and fiproles (fipronil and its degradates) that are often detected at concentrations that exceed toxicity thresholds. In response to high frequencies of detections and exceedances of toxicity thresholds, CDPR has taken three respective mitigation actions to reduce concentrations of pesticides of concern. Aniela will provide an overview of the science-drive development of these mitigation actions.

Aniela received her B.S. in environmental engineering from the University of Florida and earned her Ph.D. in environmental engineering at Carnegie Mellon University. She completed a post-doc at Colorado School of Mines before joining CDPR.

The event is a seminar-style presentation followed by a Q&A.

ABSTRACT:
Scientists encounter ethical issues while doing science, while working among other scientists, and while working within society. Today we will think about how to approach ethical issues in general. Then we will look at the ethical issues we encounter in dealing with other scientists. Scientists work daily with other scientists – as collaborators and coauthors, as supervisors and supervisees, as mentors and mentees, as referees and reviewers, as role models and advisors. All these activities have ethical components.

BIO: Sandra C. Greer
Sandra Greer received her B. S. in chemistry in 1966 from Furman University in her home town of Greenville, SC. She received her Ph. D. in chemical physics from the University of Chicago in 1969, then spent nine years as a research chemist at the National Institute for Standards and Technology in Gaithersburg, MD.

In 1978, she accepted a professorship in the Department of Chemistry and Biochemistry at the University of Maryland in College Park, MD. She chaired that department in 1990-1993. In 1995, she accepted a joint appointment in the Department of Chemical and Biochemical Engineering. In her research career, Dr. Greer was an experimental physical chemist focusing on the thermodynamic properties of solutions, including phase transitions and polymer solutions.

After 30 years at the University of Maryland, Sandra moved to Oakland, CA, to serve as Provost and Dean of the Faculty at Mills College — and to live near her twin sons and (later) her two grandsons. She retired in 2015 and is now writing and speaking. Her book “Elements of Ethics for Physical Scientists” was published by the MIT Press in 2017. She is at work on an undergraduate textbook on the chemistry of cooking

In 2004, she was awarded the American Chemical Society Francis P. Garvan-John M. Olin Medal, and in 2014 she was awarded the ACS Award for Encouraging Women into Careers in the Chemical Sciences.
