Our daughter Sylvia Bluma Katz

February 23rd, 2014

Our daughter, Sylvia Bluma Katz, was born at home here in Atlanta at 7 AM on Sunday, February 9, 2014. The midwives at Atlanta Birth Care helped with delivery. She weighed 6 lbs 2.5 oz and was 18.5 inches long. Mother and daughter are doing well, now 2 weeks since birth. I named her at Chabad Intown in Midtown, and we sponsored a Kiddush for her this past Shabbat.

Sylvia Bluma is named for her great-grandmother Sophie on my wife’s side, and her great-great-grandmother Blanche (Blima) on my side.

It has been nice having a number of visitors, including grandparents all here the week after birth. Amy and I are very excited to have welcomed Sylvia to the world!

Website fixed! Back to writing again

December 24th, 2013

Earlier this year my website developed an error that prevented me from logging in. Something about deprecated lines in the code. I use wordpress to avoid having to deal with html much, so I really didn’t know what to do, and I couldn’t access anything anyway since I couldn’t log in. Now and then I would try to find a solution to the problem, but had no luck. It wasn’t until this morning that I found the answer, where I had to replace “& new” with “new” in one spot in the background wordpress code. Now it’s fixed!

I’ve been keeping track in my phone about things I would’ve written here had I had a working website. In order to move ahead, I’ll just list out what those things were chronologically, and get back to posting regularly about current topics.

  • In March, I served on a panel at the Undergraduate Scholars Program Administrators Association’s annual Scholar Summit. It was held on Georgia Tech’s campus, and they gathered local alumni from scholarship programs to discuss with the current students about life after graduation. I served, as a representative of the Park Scholarship program at NC State with three other local alumni (one a Park Scholar from Ithaca College - our scholarship brethren). There were two NC State Park Scholars there and they were amazed to hear that it was my friends that turned the Krispy Kreme Challenge into a fundraiser.

  • A paper I helped write while interning at the Institute for Transportation Research and Education was published in the Public Works & Management Policy journal. The paper, titled “Business Perceptions of Access Management Techniques”, discusses the perceived and actual effects of median installations on highway corridors.  It was released online in July and will appear in a future issue. The abstract can be found on their site, and I will post the PDF in the Writings section as soon as I have it.
  • My wife and I bought a house in the Grant Park neighborhood of Atlanta in July, placing us in close proximity of the actual park Grant Park and Turner Field (before the Braves move away in 2017). We’ve made it home over the past half year, and are always working to improve it. It’s a 1920s bungalow style home, with the attic converted to a second story about six years before we bought it.
  • My final paper from my Ph.D work at Georgia Tech was published in the Journal of Air Transport Management. Titled “Revenue and Operational Impacts of Depeaking at U.S. Hub Airports”, it will appear in the January issue of the journal. It was co-authored by advisor Dr. Laurie Garrow. You can read the paper here, and below is a screenshot of the paper. I’ll have the paper and citation in the Writings section.

  • About a month ago, I was asked by NC State to perform a mock interview for NC State’s Marshall finalist. Because she was currently studying abroad, they couldn’t do the typical process of doing a mock interview at NC State before she came to Atlanta to interview at the British consulate. Instead, they gathered local NC State alumni to help the student out. My wife participated as well since the student was dual major with English (one of my wife’s degrees).

Besides these notable events, I have been enjoying my work at Delta immensely. During the summer, my team in Network Strategy broke off to form a new group within our department called Long-Term Planning and Competitive Analysis. Our work remained the same, but the split-off showed the emphasis Delta was putting on future network plans. I have become responsible for running three models in SAS that deal with the airline network, one which I helped produce a major overhaul this past summer. I have also gotten involved with smaller visioning projects that focus on certain geographies or industries.

Starting Work at Delta

January 6th, 2013

This week I will be starting employment at Delta Air Lines. I will be working out of their Atlanta headquarters as a specialist in Network Strategy, part of the Network Planning department. My responsibilities will include analysis on Delta’s route network and its performance, assessing areas for growth, and long-term planning.

Presentation to Boeing

December 21st, 2012

This past week I was invited to lecture at Boeing Commercial Airplanes at their Seattle headquarters. Traveling with my advisor Dr. Garrow, I presented a shorter version of my defense, discussing the revenue impacts of airline hub depeaking. An audience of about 40 Boeing employees in their sales group attended. Below is a photo of model Boeing aircraft in the lobby of their headquarters.

It was my first trip to Seattle, so during my visit, I also went to check out the University of Washington rowing’s regatta venue. It is located in the Montlake Cut on the south side of campus.

Doctoral Degree Graduation at Georgia Tech

December 16th, 2012

This past Friday, I graduated with my Ph.D in Civil Engineering from Georgia Tech. The ceremony was held at the newly renovated Georgia Tech basketball arena, the McCamish Pavilion, for all Master’s and Ph.D graduates. My parents and my in-laws came into town to see me receive my degree. The graduation speaker was Ralph J. Cicerone, President of the National Academy of Sciences. My advisor, Dr. Laurie Garrow, hooded me on stage. Below is a photo of Dr. Garrow and myself after commencement.

Doctoral Dissertation Submitted and Approved

November 14th, 2012

My Doctoral dissertation, entitled Revenue and Operational Impacts of Depeaking Flights at Hub Airports, was submitted this week to Georgia Tech’s Graduate Studies office, and I have received notification that it has been accepted. With the dissertation complete, I will graduate this December with my Ph.D in Civil Engineering. The dissertation can be downloaded at the above link, or from the Writings page.

The document has been my focus over the past two years, and I received guidance from my advisor Dr. Laurie Garrow, as well as committee members Drs. Jorge Laval, Michael Rodgers, Jeffrey Newman, and Matthew Higgins. The dissertation is an examination of the effects of schedule depeaking (also known as implement a rolling hub or continuous schedule) on airline and airport revenue and operations. I develop a way to measure depeaking and and build upon past studies that have examined depeaking for its cost effects. I studied six different cases of depeaking in the first part of the 2000s and analyzed them to see what factors played a role in shifts in revenue. In addition, I explored how airlines depeaked their schedules and what decision making processes they used to change flight frequency to spoke airports.

Passed Doctoral Defense

November 12th, 2012

Last Tuesday, I presented my doctoral work to my committee and a crowd of students. The presentation entitled “Revenue and Operational Impacts of Depeaking Flights at Hub Airports” was about 50 minutes long. After the presentation, the audience was given time to ask questions. They were then excused, and I faced the committee’s questions. After about 40 minutes of questioning, they excused me from the room so they could deliberate. I was invited back in after 15 minutes and informed than I had passed!

I will be posting my completed dissertation later this week, and including it in the Writings section.

Ph.D Defense and other updates

October 29th, 2012

I haven’t posted in awhile because I’ve been preparing my dissertation for my committee. The past few months have involved extensive writing and polishing of my results. I submitted my dissertation last week, and now am preparing my presentation for my doctoral defense scheduled for next Tuesday, November 6. It will be held at 11:00 AM in Room 1103 of the U.A. Whitaker Biomedical Engineering Building. The title of my dissertation is: “Revenue and Operational Impacts of Depeaking Flights at Hub Airports”.

My committee which I finalized in August consists of five members, one of which was required to be a faculty member at Georgia Tech outside of the School of Civil and Environmental Engineering. My committee is:

Dr. Laurie Garrow, Committee Chair
Dr. Jorge Laval, School of Civil and Environmental Engineering
Dr. Michael Rodgers, School of Civil and Environmental Engineering
Dr. Jeff Newman, School of Civil and Environmental Engineering
Dr. Matthew Higgins, Scheller School of Business

Between writing and running lots of SAS code, I have been interviewing for positions for after graduation. I applied to around 50 positions. So far I have interviewed with Delta Air Lines, LeighFisher, Ricondo, and Sabre Holdings. In the next few weeks I will consider my offers and prepare for a move (if necessary).

A paper I prepared from this work for the Airport Cooperative Research Program Graduate Award Program entitled “Depeaking Schedules: Beneficial for Airports’ and Airlines?” will be presented at the Transportation Research Board Annual Meeting in Washington, D.C. in January.

Wedding

October 29th, 2012

About five months late now  (I haven’t thought to post while writing my dissertation). On June 3, Amy and I were married in Miami Beach, Florida at the Alexander Hotel. Recently, our JDate story was posted as a success story on their website. Below is a photo of us on our wedding day, and others can be found on the Altmix Photography blog.

Paper in Print - Journal of Public Transportation

August 2nd, 2012

My next paper has been officially published in the Journal of Public Transportation. The National Center for Transit Research’s website posted the announcement for the paper in the most recent issue of the journal. The paper “The Impact of Bus Door Crowding on Operations and Safety“, was published in the Journal of Public Transportation on pages 71-93. I uploaded the publication copy to the Writings section of the site. Below is a screenshot of the start of the paper as it it appears in the journal.
