NCAR GV taking off from Guam airport, 19 Jan 2014, for Research Flight 4 of the NSF CONTRAST field campaign

University of Maryland PhD Dissertations

The doctoral defense marks an indelible day in the life of an academic.  The dissertation research is presented in a public seminar; anyone attending can ask questions.  Typically, following the public presentation, the student meets privately with their dissertation committee.  At this time more questions are asked.  The committee then meets in private and decides whether to accept the dissertation as submitted, to request changes that can range from minor to major and may or may not require a re-evaluation of the document, etc.  More often than not, the student is deemed to be a "Doctor of Philosophy (PhD)" at this meeting, and is greeted as "Dr." for the first time by their committee.  Following this meeting, most students get to return to a normal sleep cycle for the first time in many months, then are left to grapple with the question "what next?".

Dr Anderson, Dr Goldberg, Dr Nicely, and one proud adviser.

Below is a list of the doctoral dissertation defense committees on which I have served.  When available, a link to the slides presented at the defense has been provided.  Also, I've done my best to provide either a current link for each graduate, or a researcher ID page that shows the present affiliation of the UMD alum.


As of most recent update, I've served on 19 doctoral defense committees, which averages to 2 per year (or 1 per semester) since my start at UMD in September 2007.  Of course, some years have more dissertations than others. The gap in 2013 and 2014 was due to the need to focus on the logistics of the CONTRAST mission followed by initial analysis of collected data.  And, I've served on a handful of other committees as the so-called Dean's Representative.  I've only listed those for which I served on the actual, academic committee.


Each dissertation is about 180 pages; 19 180 = 3420 pages.  Prior to the defense, each page of every dissertation has been read (welcome to email any of the folks below for confirmation).  It's been a pleasure to be able to read these dissertations, each of which describes an advancement of the state of knowledge in the fields of either atmospheric chemistry, physics, or climate.


The Digital Repository of the University of Maryland (DRUM) provides an easy to access PDF record of the dissertation for all of the committees on which I have served.  As such, have done my best to use the actual DRUM URL.

University of Maryland Undergraduate Gemstone Dissertation

The UMD Gemstone program is a four-year program of research, culminating in a dissertation, for undergraduate honors students.  Freshman participate in a Gemstone orientation prior to the start of their freshman year.  During February of the freshman year, faculty present students with possible research topics.  Students form research teams and conduct research on the selected topic, during the rest of their ~3.5 years on campus.  Current Gemstone teams are posted at link.


During their senior year, the Gemstone teams make a public presentation of their team's dissertation findings to a panel of "discussants", who have also received a draft copy of the dissertation document.  The room is filled with family members, classmates and friends, as well as freshman Gemstone students who are being exposed to the end product of many year's hard work and creative thinking of the senior Gemstone Research Team.  Following the student presentations, discussants ask a single question, then anyone in the audience is invited to ask questions.  Once the public discussion has ended, the Gemstone Research Team meets privately with their faculty adviser and the discussants.  Of course, a celebration typically follows this last meeting.


In 2010, I had the privilege of serving as a discussant for the dissertation submitted by the "Carbon Sink" Gemstone Research Team. The 14 members of this research team used field research, a set of laboratory experiments, and computer modeling to quantify the effectiveness of carbon sequestration by burial of dead trees, as a means to offset rising levels of atmospheric CO2 due to the burning of fossil fuels.  The research of team Carbon Sinks was supervised by Professor Ning Zeng of UMd AOSC and Jay Gregg, a research assistant with the Joint Global Change Research Institute.  The dissertation submitted by Team Carbon Sinks was comparable to a PhD dissertation!



My Doctoral Dissertation

Alas, my doctoral dissertation, entitled Antarctic Ozone: Theory and Observation was completed in 1988, prior to the advent of PDF files! According to the great and irrefutable resource called Google, Adobe Acrobat was the first software program capable of reading the PDF format ... and Version 1 of Adobe Acrobat launched in June 1993. As such, my dissertation is archived only via microfiche at places such as link1 or link2.

Trust me, it is not worth the time, effort, or $$$ to obtain a copy of my doctoral dissertation. All that is important was published in the peer-reviewed literature long ago.  Archives of my dissertation still exist, albeit in a now archaic format. It is fascinating that we live in a time when our means of communicating information is changing so rapidly.  Should anyone actually want to see my doctoral dissertation, stop by my office and I'll gladly show you the bound edition.

The important lesson of the above two paragraphs, one I do my best to impart upon my students, is that few people will ever read a doctoral dissertation.  Basically, the committee and a handful of students to either follow in the same research group or perhaps working on a similar topic in another group, constitute the very limited audience of a document that ostensibly plays such an important role in the life of a scholar.

However, many people will read the peer reviewed articles that result from a doctoral dissertation.  As such, getting scientific results into the peer reviewed literature is the most important part of a graduate education so that:

a) findings are communicated in a manner that has transitioned, and almost certainly will continue to transition, with developments in the means of communication (all of my papers are accessible in the form of PDF files; journals have much stronger motivation and better resources to make this transition than universities, even those of high standing with large endowments);

b) the student learns the ins and outs, idiosyncrasies, struggles, frustrations, and ultimately (hopefully) joy of publishing.  Yes, we have been known to shed a tear of joy upon receipt of an email from an editor stating a paper has been accepted.  For an academic, a day when such an email has been received can rarely be topped ... other than, of course, getting an email stating a grant proposal has been accepted!

Only fitting to conclude by providing the link to our group's publication page.
