Name that Bloodsucker! Interview with Eric Engh

by Shoshana Harlem, Terra Linda High School

Eric Engh, an insect ID Specialist, works for the Marin-Sonoma Mosquito Vector. He also runs educational programs for the Marin-Sonoma Mosquito Vector. He has a Bachelor's degree in Environmental Studies and an M.S. in Entomology from University of Florida.

1. What made you want to study insects?
 I have been interested in insects ever since I was a small child. I was also really lucky to have an excellent mentor- Ron Keith. He was our Vector Ecologist for Marin/Sonoma Mosquito and Vector Control District for over 30 years. Not only did he teach me much about entomology, he excelled at explaining information in a friendly and simple manner without making the listener(s) feel stupid. In the 5 years that I got to work with him, I got to see him help hundreds of people with their entomological inquiries.

2. What are the best parts of your job? What are the worst?
I don’t really have any complaints about my job. I enjoy teaching about entomology, developing curriculum and interactive displays for public events, and I really enjoy being a resource of information for the public. The most difficult part of my job has to do with people who are convinced that some unseen insect is biting/infesting them, but there is no concrete evidence to support this. There are many causes of skin irritation similar to an insect bite that include but are not limited to: environmental sensitivities, allergies, reactions to various chemicals or medications, mental conditions, etc.. These cases can be very difficult because the person is absolutely convinced they have an insect infestation, and they often have already been turned away by doctors, family members etc., and are extremely frustrated. I can identify insects, but in these cases there is little I can do to help, and resources available for people with these problems are scarce.

3. How can people protect themselves from being bit by mosquitos?
There are many things people can do to protect themselves from mosquitoes:
Wear EPA approved mosquito repellent while spending time in areas where mosquitoes are present.Search around your home for any source of still water where mosquitoes may breed. Dump out small amounts of water that accumulate in items that don’t require water (buckets, toys, junk, etc.), rinse out items that require small amounts of water (bird baths, pet water dishes, etc.) at least once a week. Don’t ignore mosquito problems! Call the Marin/Sonoma Mosquito and Vector Control District for help locating unknown sources of mosquitoes or to help with a mosquito-related problem that you cannot resolve on your own.

4. What should people do if they get bit by a mosquito?
The most important thing to do is to not make the problem worse by itching the bite site and scratching open the skin, which invites infection. There are over-the-counter products that are commonly available to help reduce itching sensation, or if someone has a serious reaction to a bite, they should consult a doctor.

5. What current projects are you working on?
I am currently working to create a curriculum for local vectors (mosquitoes, ticks, yellow jackets), that reinforces the Next Generation Science Standards. We provide an education program to schools, and we are trying to make it interesting, useful and informative. We are also involved in a number of other projects including surveillance for invasive species of mosquitoes.

Invention in Medicine this Wed. 10/26/16

Marin Science Seminar for Teens & Community Presents Invention in Medicine How Medical Devices get Invented and Go to Market with Art Wallace MD PhD of UCSF & VAMC SF
Wednesday, October 26, 2016 7:30 - 8:30 pm Terra Linda High School, Room 207 320 Nova Albion, San Rafael, CA 94903 


Art Wallace started out in experimental surgery and radiology studying imaging of the heart using CT
scanners. He has worked on a number of devices that originally were built for experimental studies that evolved into clinically useful devices including a cardiac output monitor, the off pump CABG, off pump aneurysm surgery, electronic sedation, and a selective coronary vasodialtor. Dr. Wallace will explain his experiences with the inventive process using examples from both device design and drug development. There will be a brief discussion of the importance of intellectual property, patents, venture capital, FDA approval, and business development in completing the invention process. There will …

An Interview With Diara Spain, Ph.D

By Rachael Metzger, MSS Intern

Ocean acidification is an issue becoming apparent in the effects on both sea creatures and humans. Diara Spain, the Associate Professor of Biology at Dominican University, came to Marin Science Seminar to talk to us about her studies in marine invertebrates and the damage ocean acidification is causing them. 

To learn more about Diara Spain and what inspired her studies we conducted an interview:


1. How did you get interested in biology? Is there a time, event, 
or person in your life that inspired you to pursue the study? I've always been interested in biology, really science in general. I grew up in rural North Carolina and as a kid it was expected that you'd spend most of your free time outside playing with your friends and pets.  One thing that sparked my interest in marine organisms were the summer vacations at the undeveloped beaches in North Carolina. 
2. Why did you specifically decide to focus on functional morphology, locomotion in echinode…

Marin Science Seminar Internships Still Available

Marin Science Seminar still has two high school student internship spaces available. Interns must be able to attend science seminars on select Wednesday evenings at Terra Linda High School in San Rafael. Interns arrive at 7 pm to set up, assist with the seminar, and can leave when the seminar is cleaned up by 8:45 pm. Specialties are also available for students interested in writing, photography, videography, and social media.
