Related Online Degrees & Career Pathways

Exploring Ecology and Evolution opens doors to a variety of interdisciplinary career options. Many students complement their scientific expertise with skills from related fields through online advanced degree programs, which can lead to broader roles in research, education, and policy.

For those interested in community engagement or social change, msw online programs provide training for impactful roles in social work — including advocacy for environmental policy and community development. Alternatively, students seeking a quicker route to specialization in human behavior can pursue a 1 year master's in psychology online to accelerate their career in research or environmental education.

Those passionate about mental health within ecological contexts can enhance their credentials with an online masters in mental health counseling. Graduates can advocate for well-being among communities impacted by ecological change.

A background in ecology can also pair well with forensic science. By obtaining expertise in areas such as forensic psychology, students may wonder what can you do with a masters in forensic psychology, which can include roles in environmental crime investigations or legal consulting.
