When you walk into Eunha Hoh鈥檚 lab housed deep inside Hardy Memorial Tower, it鈥檚 a hub of thriving research activity. An environmental scientist within the School of Public Health, Hoh supervises undergraduate and graduate students who analyze air and water quality and their impact on humans, animals, and birds.

Many of her students come from pure science backgrounds and in  have found a pathway to apply their theoretical learning in practical ways that help mankind. 

Jade Johnson is a first-year graduate student in environmental health science studying the removal of contaminants for wastewater recycling. She began doing research in Hoh鈥檚 lab as a chemistry undergrad. 

Maggie Stack, a second-year grad student, relocated to San Diego from Maine to join Hoh鈥檚 lab and study the impact of contaminants on the California condor. She majored in biology as an undergrad. 

Pamela Olguin, a first-year master鈥檚 student, was given a referral to Hoh as a Grossmont College transfer student pursuing a bachelor鈥檚 in chemistry, because of her interest in anti-smoking advocacy. She studies the impact of exposure to smoking.

Hoh is one of many professors at 色情视频 who encourage undergraduates to pursue research and offer lab research opportunities. 

鈥淚 like training undergrads because I want to make sure they understand their degrees are very valuable and to show them the career paths that are possible,鈥� Hoh said. 鈥淭hey鈥檙e often not aware of how to apply their learning to public health and the tangible problems in society.鈥�

She recalled how as a chemistry undergrad herself, she did not know about all the potential pathways. 鈥淭hat鈥檚 why I want our students to be highly motivated for the basic improvement of society, instead of wondering 鈥榃hat am I doing here?鈥� When I found this path, I was super motivated.鈥�

When she is looking for students to join her lab, she calls the undergraduate advisors for biology, chemistry and environmental science. Grad students mentor undergrads, training them on instrumentation and lab processes, and second-years mentor first-years, creating a collaborative work environment. 

Here is a closer look at three current projects.  

Cross-disciplinary research

Jade Johnson splits her time between two labs on campus. 

She collects wastewater samples and operates a lab-sized treatment system at associate professor Natalie Mladenov鈥檚&苍产蝉辫; in the Department of Civil, Construction, and Environmental Engineering. There, Johnson studies the efficiency of decentralized wastewater treatment technology in removing contaminants.

Johnson then brings the wastewater samples to Hoh鈥檚 lab where she uses state-of-the-art analytical instrumentation, such as two-dimensional gas chromatography coupled with mass spectrometry, to analyze for trace organics and find contaminants of concern. The two professors collaborate on a joint National Science Foundation funded project.  

Johnson was born on a Navajo reservation in Arizona near Grand Canyon National Park, grew up in a town very close to it,  and is the first in her family to graduate with a STEM degree and attend graduate school. As an 色情视频 undergrad, she found out about the(Maximizing Access to Research Careers) fellowship for underrepresented students and the  funding. 

She applied to both, and through her mentor at the  (NARCH), sought a referral to Hoh and has worked with for the past three summers.

鈥淩esearch opportunities differ from lab to lab. In professor Mladenov鈥檚 lab, we work independently and figure things out on our own,鈥� Johnson said. 鈥淧rofessor Hoh is a pioneer in her field and I like how interdisciplinary the work done here is, and how it connects so many fields and informs public policy.鈥� 

Helping endangered condors

Maggie Stack receives funding from the California Sea Grant to research the impact of environmental pollutants on the California condor, which is critically endangered. The project is a collaboration between 色情视频 and the San Diego Zoo. 

She heard about Hoh鈥檚 research from a friend while working at a non-profit in Blue Hill, a small town in Maine, where she studied microplastic pollution in marine animals such as dolphins. So Stack flew out to San Diego to meet Hoh, visit the lab and see if it would be a good fit before applying to the MS program.

鈥淓veryone tells you to make sure you find a good advisor for grad school. Right off the bat, I could tell she cared about her students,鈥� Stack said. 鈥淭he condor project was fascinating.鈥�

At one time the condors were nearly extinct, but a captive breeding program initiated by the zoo with other collaborators has helped boost their dwindling numbers to more than 500 now. But they are experiencing reproductive stress, so Stack monitors their health by procuring blood samples that she analyzes for contaminants in Hoh鈥檚 lab. 

Tracking smoke exposure

Pamela Olguin participated in anti-smoking advocacy as a high school student, which eventually led to her current research on smoke exposure.

She applied to , a joint program at the University of California, San Diego and 色情视频 for transferring students, that comes with a paid summer internship. She was referred to Hoh who is one of several 色情视频 researchers involved in smoking research. 

鈥淚 learned how chemistry is widely applicable outside of sciences, and how it can be used in a public health lab, and how to present my work,鈥� said Olguin, who studied thirdhand smoke, the toxic residue from tobacco smoke.

By senior year, her research experience influenced her to pursue a master鈥檚 in environmental science. She now studies polycyclic aromatic hydrocarbons, a complex compound present in cigarette smoke, and tracks what people absorb by giving them a silicon wristband to wear which absorbs chemicals to which they鈥檙e exposed. 

She recommends students interested in applying to labs do their homework first.

鈥淩esearch your professors beforehand, read a couple of their papers, make sure it鈥檚 something you鈥檙e interested and go talk to them. They鈥檙e all willing to take you in because undergrads can be so useful in labs.鈥�
