Photos from recent ISPTS conference held at UC Riverside

In late November, UC Riverside hosted the International Symposium on Persistent Toxic Substances.  Prof. Jay Gan took the lead on organizing the symposium which was an impressive event consisting of plenary sessions, multiple concurrent sessions, a reception, lunches, a banquet, etc.  There were a number of excellent presentations including prominent speakers in the field, and almost 300 people attended.  It was particularly enjoyable to see the involvement of students, led I believe by Stacia Dudley, one of Jay Gan's graduate students, who took care of many of the local arrangements.  Below are photos from the symposium.  Our thanks to Jay and his team for organizing such an outstanding conference.

The message below was forwarded to me earlier today.

The ILSI North America Technical Committee on Food and Chemical Safety is sponsoring a summer fellow to work on a case study for a food-related chemical using the RISK21 approach for evaluating and comparing the applicability of traditional toxicology studies and complex data sets generated by in silico and HTS technologies in chemical safety assessments. The deadline to apply is Friday, 29 January 2016.

The announcement is also posted on the ILSI North America website:

We would like to request you to share the attached announcement with your graduate student members (Risk Assessment Specialty Section, SOT) who might have an interest in applying.

Terrible Tragedy Too Close to Home

As you are probably aware, this past week there was a domestic terrorist attack just to the north of Riverside, in San Bernardino, in which 14 people were killed and 21 injured.  Two of those killed and two of the injured were alumni from UC Riverside.  Of particular note, one of the injured was Jennifer Stevens who graduated in Environmental Sciences with an emphasis in Environmental Toxicology this past June.  She was enrolled in two of the classes that I taught last year.  She is a fine young woman, and we hope that she has a speedy and complete recovery.  In the photo above, the flags in Washington, DC (and on U.S. government buildings throughout the world) are at half staff today and tomorrow in respect for those in San Bernardino who lost their lives or were injured in the attack.  We wish for the best for the survivors and their families as well as for the families and loved ones of the deceased.

Postdoctoral position at UC Santa Barbara

I received the following position information earlier today by email. The position is with Roger Nisbet at UC Santa Barbara. 

Applications are invited for a post-doctoral specialist to participate in systems-based research for evaluating ecological impacts of manufactured chemicals. The overarching aim is to use Dynamic Energy Budget (DEB) models to inform ecological risk assessment by determining how the effects of exposure to chemical stressors are expressed across levels of biological organization.  Specific projects include: (i) determining how genomic data on two model organisms (the waterflea Daphnia and the estuarine fish Fundulus) experiencing combined food and chemical stress relate to parameters in DEB models; (ii) predicting organismal and population “tipping points” caused by failure of physiological and population regulatory processes; (iii) developing individual and population models of adaptation to stress in chronically polluted environments.  The person appointed would work on one or two of these projects.

The research is part of a recently funded project led by Dr. Roger Nisbet (UCSB), working in collaboration with Dr. Erik Muller (UCSB) and Dr. Andrew Whitehead (UC Davis). UCSB is renowned for its quantitative ecological research and has a number of faculty involved in ecotoxicological research projects. There will be opportunity to interact and collaborate with researchers in the University of California Center for Environmental Implications of Nanotechnology (

Applicants must possess a PhD and have research experience in one or more of theoretical ecology, environmental modeling, systems biology, or closely related disciplines. The position is for 2 years, contingent on funding. Start date: 1 January 2016 or as soon as possible thereafter.

If you encounter anyone at ESA (or know of anyone) who might be interested, please encourage them to email me. Dr. Nisbet's email address is:
