We are looking for motivated students to apply to the Ecology, Evolution, and Environmental Biology Department for our PhD and MA programs. If you are interested in joining the lab, please e-mail Maria Diuk-Wasser with your CV and a short statement on: a) your background and research interests; and b) how these interests align with the work of the lab (i.e., what aspect of vector-borne disease eco-epidemiology you would like to work on).

We are looking for summer research assistants!

We have several paid positions for highly motivated Research Assistants to support research and outreach activities for the 2022 field season. The project will evaluate factors influencing the distribution of mosquito, ticks and associated pathogens across an urbanization gradient in New York city, Long Island and Block Island, RI. The assistants will support our team with one or more of the following activities depending on their experience: general fieldwork planning and logistics, mosquito and tick sampling in natural areas, vegetation surveys, and host sampling using camera traps and live trapping. This position will provide strong training in conducting ecological and epidemiological surveys in the field, tick and mosquito collection and identification, data management skills, and science communication. 

Primary responsibilities (one or more of): 

  • Conduct ecological assessments of natural areas, including tick, mosquito, small mammal, vegetation, and camera trap sampling in natural areas.
  • Coordinate field logistics and data management with a field crew of 3-4 assistants.
  • Manage public outreach activities (online and in-person), including preparing and distributing announcements and reports, attending public events, and updating website and social media.


Requirements: Applicants should have a keen interest in disease ecology/environmental health/epidemiology/public health, have strong leadership and communication skills, and be highly organized with legible handwriting. A valid U.S. driver’s license and clean driving record is required. Experience with tick, mosquito, small mammal or bird sampling and identification, as well as with public outreach are desirable. This may be a fieldwork intensive position, so RAs must be in good physical condition and be capable of working in unfavorable environmental conditions (e.g. rain, heat, tick-infested habitat). In line with Columbia’s current COVID-19 vaccination mandate, full vaccination, including booster doses, is required. 


Dates/Hours: This is a full-time, temporary and seasonal position beginning in April and ending in August 2022; exact dates are somewhat negotiable. 


Wages/Benefits: Housing, field equipment, and transportation within the study area may be provided; current residence in New York and car availability will be considered a plus. Jobs are full time, 35-40 hours/week.  Wage is commensurate with education and experience. 

TO APPLY: Applications can be accessed online through the google form below. You will be required to provide a list of three professional references, as well as a cover letter outlining relevant field experience and a CV/resume. Please provide these in a single pdf document with your last name in the subject. Application review will begin on March 16th 2022 and continue on a rolling basis.

We are looking for a Laboratory Technician!

Position Summary

The Diuk-Wasser in the Department of Ecology, Evolution and Environmental Biology is looking to hire a part time lab technician for molecular and field work on tick-borne disease pathogens.

** This is a 12-month term appointment with the possibility of extension contingent on successful performance and continued funding.


The lab’s work focuses on studying the ecology of tick-borne pathogens by collecting field samples during the summer months, conducting quantitative PCR and tissue culture, and animal-tick transmission experiments during the academic year (see https://ecoepidemiologylab.e3b.columbia.edu). The technician would assist in all these activities, help order reagents for the lab as well as help coordinate and prepare for the field sampling season.

  • Conduct DNA extractions and quantitative PCR. 30%
  • Project management for the Diuk-Wasser Lab. 25%
  • Collect field samples during the summer months. 20%
  • Coordinate and prepare for the field sampling season. 15%
  • Help order reagents for the lab.  10%

The ideal candidate will have experience with DNA extractions and quantitative PCR, will have previous field experience (not necessarily collecting ticks) and have experience working with laboratory animals (optional). The candidate should have a strong interest in disease ecology and will participate in providing support to students and postdocs in the lab. The candidate should have excellent communication skills, have meticulous attention to detail, and exhibit strong project management skills.

Minimum Qualifications

  • Bachelor’s Degree in the biological science.
  • Two years of experience in a research environment.
  • Experience working in a molecular laboratory and some field experience.

Preferred Qualifications

  • A graduate degree in Ecology/Biology/Evolution and experience in pathogen screening.
  • Strong dedication and organizational skills evidenced in recommendation letters (2 letters required)
  • Molecular experience: DNA extraction, quantitative PCR.
  • Field experience
  • Laboratory animal experience

Equal Opportunity Employer / Disability / Veteran

Columbia University is committed to the hiring of qualified local residents.
