Contributions to Teaching, Leadership, and Access

Below are some of my materials prepared for introductory college and university upper-division teaching, and recent contributions to social justice in STEM. I have taught laboratory components of oceanography, mineralogy, petrology, and general geology classes.

Teaching

Rocks have never been self-explanatory, yet the pace of undergraduate geology courses seem to suggest they are. When teaching, especially in laboratory sections, I create opportunities for students to practice “seeing” and recognizing patterns, while being sensitive to disability and strategies to incorporate universal design.

Optical Mineralogy Concepts in Video Format

Description

This screenshot shows a view from an instructional video I created for undergraduate optical mineralogy students to distinguish between two minerals, clinopyroxene and orthopyroxene, in thin section under two types of light (plane polarized light, also referred to as PPL and cross polarized light, referred to as XPL). In this video, the same view for each mineral to demonstrate differences in extinction. Difference are also noted in annotations. Watch video on YouTube.

Thumbnail showing two views of mineral under microscope. Left side shows straight lines across light background. This is clinopyroxene under plane polarized light. Right side shows same view under cross polarized light where the light areas are now all dark. This indicates that this is clinopyroxene, because the lines do not align vertically, but are diagonal.

Sample narrative for teaching

This video shows how one might use cleavage traces of two unknown pyroxene minerals for identification. Set up the view of the mineral in plane polarized light.

  1. Locate cleavage traces (dark lines) and align them so they are vertically aligned up/down with crosshairs. This will be the starting angle to test for parallel extinction.
  2. Switch to cross-polarized light and observe if extinction occurs while remaining in this view.
  3. If the mineral remains extinct without rotating the stage, then the extinction angle is 0 degrees That means this has parallel extinction and is likely orthopyroxene1.
  4. If I must rotate the stage to see extinction, then this means the extinction angle is greater than 0. This indicates inclined extinction, and the mineral is clinopyroxene

Leadership

Unpacking Diversity Keynote Event, 2021

“Transforming the culture of geosciences” in 2021 with Dr. Aradhna Tripati was a multi-year effort at the institutional and community level.

Key Details

I coordinated multiple aspects of a 2021 keynote event with Dr. Aradhna Tripati (UCLA, CDLS). Planned initial conception of in-person event in October 2019 to execution of virtual event in May 2021. The first year’s planning efforts resulted in an original date, late May 2020.

After much uncertainty amidst the pandemic, we successfully held the event during a 2-day “virtual” keynote visit, with ~$1,000 more support than the previous year, thanks to co-sponsorship by additional campus and off-campus stakeholders. To ensure audience engagement during the virtual event, the budget included accommodations for the keynote event and undergraduate student participation in a workshop.

This event reflects continued efforts and success in delivering relevant and timely educational events, whether they are in-person, hybrid, or virtual.

Contributions

  1. Created and maintained project planning document and timelines. Led communication with speaker, vendors, on-campus and external stakeholders, and revised plans and timelines as needed throughout the process
  2. Prioritized accommodations in the budget, communicated with OSU DAS to coordinate appropriate vendors for captioning/ASL interpreters. Prepared event glossary and introduction script
  3. Ran keynote event with Zoom Webinar500 platform, set up registration page and backend settings for webinar, wrote scripts, prepared run-of-show documents, tested event with captioners and interpreters and test users, set up livestreaming options.

Compiling and presenting NSF demographic data in the geosciences

Motivation

Inspired by Dr. Rachel Bernard’s paper, titled No progress in geoscience for 40 years, and Dr. Bernard’s blog post during her PhD years, where data from 1973-2016 pointed to a worse outcomes for Black and Indigineous students in geoscience.

When new data from the NSF Survey of Earned Doctorates was released in 2020, I was motivated to see if two years of additional data (2017, 2018) would show the same trends that Dr. Bernard found. I compiled the new data and created these plots to assess if progress had occurred since 2016. These were shared on the Unpacking Diversity Twitter.

Outcomes

The line plot shows the number of U.S. Doctorates in Earth Sciences, by ethnicity between 2008 to 2018. Lines correspond to values for the following ethnicities: Total, White, Hispanic or Latino, Black or African-American, Asian, Native Hawaiian or Other Pacific Islander, More than one race, American Indian or Alaska Native.

In 2008, the total number of degree recipients was around 275, with white recipients accounting for nearly 250. In 2018, total recipients increased to about 375. White recipients make up over 300 of those recipients. Almost no change observed from 2016 to 2018.

  1. Looking down the {100} face of clionopyroxene may produce parallel extinction. Be sure to examine several grains and use other diagnostic observations to support your identification.
