  • Role
    Scientist Mentor: I will mentor teams of students online

  • Research Interests (300 words)
    My research focuses on the effects of environmental factors on the development of root systems and stress-induced programed cell death in plants.
    I am also the Director of Miami University's botanical Conservatory.

  • Do you have previous experience in mentorship or educational outreach? Please list here (200 words)
    I have been an advisor of college botany majors at the undergraduate and graduate level for 29 yr. I have participated in Planting Science since 2008. I created a children's anti-plant blindness outreach program for the entire Hamilton Ohio City School district involving in classroom activities and field trips to the Miami University Conservatory that ran for a decade and served ca. 8000 children.

  • Which of the following best describes your career stage?

  • Profile Question 1
    What was the first science experiment you ever designed? How did it turn out?

  • Answer the question you selected for profile question 1 here (300 words):
    As an undergraduate I had a lab job assisting a doctoral student who needed to isolate DNA from the root apical meristems of pea plants. We did not have polymerase chain reaction technology to amplify small amounts of DNA in those days, so he needed very large numbers of root tips to get sufficient DNA for an experiment. Based on my classwork and some experiments some other students in our lab had done, I thought I could use elevated temperature to significantly increase the number of cells in these meristems, and therefore reduce the number of root tips we would need to collect to get enough meristem DNA. The experiment was pretty much a failure with respect to its hypothesis and objective, but it serenipitously revealed a lot of surprising effects that elevated temperature had on the development of pea roots. This ultimately led to my own doctoral dissertation research project and subsequent life's work.

  • Profile Question 2
    When and why did you decide to go into a science career?

  • Answer the question you selected for profile question 2 here (300 words):
    When I was contemplating going back to college after 18 yr in other occupations, I discovered it was not necessarily required that one live and work in a city to do science. I wanted my children to grow up in a non-urban environment, so I decided to study agronomy and botany.

  • Profile Question 3
    What is best about being a scientist?

  • Answer the question you selected for profile question 3 here (300 words):
    Being able to make a living discovering new things about the world and sharing those discoveries with colleagues and students.

  • Help represent the outreach efforts of your societies. Please click all those organizations you are a member of:
    Botanical Society of America
    Japanese Society of Plant Physiologists, Scandinavian Plant Physiology Society, International Society for Plant Anaerobiosis

Dear Project Team 4:

I wish you had interacted with me during your project.  Plant photosynthesis is the most important biological process on earth, and I think it is fun to study.

Best wishes, Dr. Dan Gladish

Dear Preslea and Team 4:

Wonderful!  Thank you for all the detailed updates.  I am intrigued by the clever method you used to show the CO2 evolution from yeast fermentation.  You and I have to assume it is CO2 that…
