Emerging Investigators Series: Yu (Frank) Yang

 

 

Yu (Frank) Yang is an Assistant Professor at the University of Nevada, Reno, working in the Civil and Engineering Department. Prior to this, he completed both his undergraduate studies and PhD at Peking University, China. His current research interests include: the impact of global climate change on the fate of critical pollutants; the response of organic matter geochemistry to the temperature increases; and the colloid-facilitated reactive transport of insoluble radionuclides.

Read his Emerging Investigators article “Dual role of organic matter in the anaerobic degradation of triclosan” and find ourmore about Frank and his research in the interview below:

 

 

Your recent Emerging Investigator Series paper focuses on the role of organic matter in the anaerobic degradation of triclosan. How has your research evolved from your first article to this most recent article?

My first research paper is about the human exposure to legacy pesticides (e.g. DDT) and their health risk. My Ph.D. studies and postdoctoral projects are mainly focused on the organic matter-mediated fate and transport of organic and inorganic pollutants. In this paper, we have found an interesting novel dual role of organic matter in the degradation of an emerging organohalide compound.

What aspect of your work are you most excited about at the moment?

In my research group, we are mainly working on the important environmental redox reactions, focusing on the degradation of organohalides, microbial assimilation and plant uptake of carbon nanomaterials, and stability of soil organic carbon. We are currently using lots of state-of-the-art technologies to study the transformation of organohalides and natural organic carbon, which is really exciting to us.

In your opinion, what is the biggest impact to the environment presented by antimicrobial agents?

Release of antimicrobial agents can induce the development of antimicrobial resistance, which is one of the biggest environmental problems.

What do you find most challenging about your research?

I would like to fully understand the degradation pathways of emerging organohalides and work out cost-effective removal strategies. Both are challenging tasks.

In which upcoming conferences or events may our readers meet you?

My group and I will present our work (6 talks and 3 posters) at American Chemical Society 2017 Spring Meeting (April 2-6, 2017, San Francisco). I am also chairing two symposia with my colleagues, with one for redox reactions and the other for nanomaterials.

How do you spend your spare time?

When I have spare time, I enjoy watching movies, playing chess, and spending time with my family.

Which profession would you choose if you were not a scientist?

Without science, probably I would become a high-school teacher.

Can you share one piece of career-related advice or wisdom with other early career scientists?

Have a good balance and be persistent. Balance between the crazy ideas and relatively “low-risk” projects, balance between pursuing grants and publishing papers, balance between research and teaching, and many others

Emerging Investigator Series: Cora Young

We are delighted to be able to bring you the first in interview for our Emerging Investigators Series in Environmental Science: Processes and Impacts

Cora completed her undergraduate and doctoral studies in the Department of Chemistry at the University of Toronto. Under the supervision of Prof. Scott Mabury, her Ph.D. research focused on the atmospheric chemistry of polyfluorinated compounds and their role as long-lived greenhouse gases and sources of persistent compounds to the environment. She went on to a postdoctoral position in Boulder, CO with Dr. Steven Brown at the University of Colorado and the National Oceanic and Atmospheric Administration (NOAA). There, she developed novel, state-of-the-science instruments and used them to measure reactive atmospheric trace gases and determine their impact on the oxidative potential of the atmosphere. Cora joined the Department of Chemistry at Memorial University as an Assistant Professor in September 2012.

Read her Emerging Investigators article “A 14-year depositional ice record of perfluoroalkyl substances in the High Arctic“, which is featured in Issue 1 of the journal, and find out more in the interview below:

Your recent Emerging Investigator Series paper focuses on improving the understanding of transport of perfluoroalkyl substances in the High Arctic. How has your research evolved from your first article to this most recent article?

One of my first papers as a graduate student also involved looking at long-range transport of perfluoroalkyl substances to the Devon Ice Cap and was published ten years ago. As instrumentation improves and we develop better analytical methods, we are able to learn so much more about how pollutants impact our environment. We were able to look at four times as many chemical species as the original study, which greatly increases our understanding of the environmental fate of these compounds. We have also expanded our research network to include Northern community members and Arctic researchers with complementary expertise, which allows us to interpret and apply our results more effectively.

What aspect of your work are you most excited about at the moment?

We have some new environmental field and laboratory samples, including ice cores and biomass burning smoke samples, that I am excited to analyze using analytical techniques recently developed in my group.

In your opinion, what is the biggest impact to the environment presented by perfluoroalkyl substances?

Perfluorinated compounds have no natural degradation pathways in the environment. When we emit these chemicals to the environment, they will remain for the foreseeable future. We know that many perfluoroalkyl molecules bioaccumulate and could affect the health of humans or animals, which is cause for concern because there is no going back to an environment uncontaminated with these chemical species.

What do you find most challenging about your research?

I find field work simultaneously the most rewarding and the most difficult aspect of my research. Addressing environmental chemistry questions often means challenging collection of samples (such as those from ice caps) or the design and/or operation of complex instrumentation under harsh conditions.

In which upcoming conferences or events may our readers meet you?

Canadian Chemistry Conference and Exhibition in Toronto, Ontario (June 2017) and Healthy Buildings Europe in Lublin, Poland (July 2017). I can also be found online at cjygroup.com and on Twitter @SVOCora.

How do you spend your spare time?

I don’t have too much of it right now! When I do have free time, I enjoy travelling, walking, hiking, reading, and yoga.

Which profession would you choose if you were not a scientist?

It’s hard to imagine my life without science! If I wasn’t a scientist, I would want to do something that still involved science, like science communication or conservation management.

Can you share one piece of career-related advice or wisdom with other early career scientists?

Seek out a supportive career network of mentors, collaborators, and colleagues. I have been fortunate to have wonderful mentors from my doctoral and post-doctoral work, and throughout the environmental chemistry community. My excellent collaborators from other academic institutions, Environment Canada (who were collaborators on this project), and National Oceanic and Atmospheric Administration improve the quality and impact of my research and make it more fun to do!

What’s new in the analysis of complex environmental matrices?

What’s new in the analysis of complex environmental matrices?

Royal Society of Chemistry

Environmental Chemistry Group, Water Science Forum and the Separation Science Group Joint Meeting

Friday 3rd March 2017

at

Science Suite, Royal Society of Chemistry, Burlington House, Piccadilly, LONDON, W1J 0BA

The analysis of environmental matrices such as water, sediments and soils is often demanding and challenging for the chemist due to both matrix effects and the myriad of substances that can be present in the sample. This one-day Royal Society of Chemistry Meeting, jointly organised by three special interest groups (Environmental Chemistry Group, Separation Science Group and Water Science Forum), addresses this issue. It is the third in sequence of biennial conferences. The meeting brings together national and two international experts on the topic. The monitoring and screening-type analyses of a wide range of both regulatory and emerging pollutants (such as pharmaceuticals and personal care products) in water is major theme of the event. The detection of potentially hazardous compounds in dusts and consumer articles is also considered. Other topics to be addressed include new types of detectors (i.e. ion mobility spectrometry, direct probe time-of-flight mass spectrometry and selected ion flow tube mass spectrometry) for measuring environmental chemicals. In addition to the lectures, there will an exhibition where number of instrument manufacturers and suppliers of laboratory consumables will be presenting.

Important Date

Registration Deadline: 28th February 2017
