Candidate Statement

 First, let me thank the Division for the confidence they have shown me through this nomination for Member-at-Large.  I have held numerous positions within the Division: Member-at-Large, Program Chair, Treasurer, and Acting Secretary.  Additionally, I co-chaired the strategic planning effort which created the first five new subdivisions for Younger Chemists, Women Chemists, Minority Chemists, Chemists with Disabilities, and those interested in Ethics.  I participated in the 2017 division strategic planning effort and led the creation of subdivision lapel pins for the six subdivisions that did not have them.  These pins have been a huge benefit as we market the division and its subdivisions to new members.  An effort which continued in November 2018 when the division hosted a networking reception at SERMACS 2018 in my local section (Savannah River) for 1550 meeting registrants.

As with most successful ACS groups, including Committees and Local Sections, much Division business needs to occur between National Meetings.  Volunteers need to be prepared to spend many more hours between official meetings conducting the business of the Society if any meaningful progress is to be achieved.  As Member-at-Large of the Division of Professional Relations, I will work tirelessly to strengthen our efforts at programming and service to our members throughout the calendar year.  I will work to enhance communications between subdivision chairs and their members.  The subdivisions are a great resource for the future health and vitality of PROF, but they need to feel they are a part of the Division as demonstrated by our programming, newsletter, and decision making processes.

Again, let me thank you for this nomination and ask for your vote if you feel I can successfully contribute to the future of the Division as part of the governing Executive Committee.

Michael currently serves as the PROF liaison to the Diversity, Inclusion, and Respect Advisory Board of the American Chemical Society. As Michael transitions into his postdoc in 2021, he wants to serve as PROF member at large to facilitate and organize upcoming PROF programming and logistics.


Ian Stark

STARK, IAN S. South Plains Section. Texas Tech University and Independent Consultant, Lubbock, TX.

Academic Record: PhD Technical Communication (in progress); MBA Healthcare Management; MA Communication; BA Communication

Honors: 95th percentile MBA graduate in national competition testing management, marketing, finance, and accounting.

Professional Positions (for past 10 years): 2020-Present: Teaching technical/scientific communication at Texas Tech University; 2017-Present: Working as independent consultant for various biomedical/biochemical organizations (ShannonMedical, Immunotrex Biologics, Texas Department of State Health Services, etc.); 2013-2016: Worked as producer for Cherry Creek Media creating advertising and public relations materials.

Service to ACS: Active in event planning and outreach for the Business Development and Management (BMGT) division.


Candidate Statement: 

My engagement with chemistry has been anything but typical, as I first came to this field from a foundation in the humanities (communication studies). In that space, I specialized in cultural engagement research and raising up the voices of oppressed groups – particularly LGBTQ+ scholars and scholars with disabilities. Along the way, Idirected dozens of outreach projects and community events, in both academic and non-academic contexts, and I believe that those experiences would be transferable to the objectives of our division. Thus, if elected as Member-At-Large, I want to bring this explicit humanitarian perspective to the Division of Professional Relations. At the end of the day, when you’re talking about people, you don’t need a “chemist” per se – you need a “communicator.”

Candidate Statement

I am running for the position of Councilor for the ACS Division on Professional Relations. After serving in numerous roles in the Division, I am eager to bring a fresh voice to speak for the professional development of chemists to the ACS Council and subsequent ACS Council Committees. I am an experienced leader within the Division, and Society, with a track record of delivering innovative and effective solutions for the professional development of all Members. If elected as Councilor, I would use the position to elevate the level of discourse and understanding of professional development within subsequent Council and Committee functions, while simultaneously increasing dialogue amongst PROF members in preparation for Council meetings so that we can properly reflect our collective voices as a Division devoted to creating diverse and inclusive communities across the Society. We may be a relatively small Division, but our focus and charge is arguably the largest and most important. I wish to represent our Division on the Society’s largest forum and amplify our community’s voice, so please support me in this effort by voting for me to ACS Division of Professional Relations Councilor.
