Those seeking employment opportunities might consider some of the companies and organizations listed in our "links" page. The departmental sectretary or placement office at your university also can be of great help. In addition, the programs at NC State have a recurring, occasional need for post-doctoral research associates.

 

Short-Courses at Your Location: Training at your site

Since about 1989 I have been delivering high-quality short courses on behalf of a diverse list of industrial clients (see list at the end of my curriculum vitae), with an effort to tailor the material to address critical needs, problem solving, and product development related to papermaking wet-end chemistry and allied subjects.

Does your company have a critical need for a better understanding of science and technology related to papermaking additives, cost-saving strategies, or papermaking process and product development?  Can some of your people benefit from a better understanding of the basics… or of recent developments? If so, I would like to suggest a way to meet this need without requiring your people to travel. 

Based on many cycles of targeted short-course delivery and consulting, working with many different clients (paper companies, chemical supplier companies, and equipment companies), what I usually recommend is that the client and I begin by defining key concepts that are most critical to be included in a “refresher” or highly targeted training session, where I can help your people to be up to speed in challenging topics within the field of papermaking chemistry.  Then, where appropriate, such input can provide a lead-in so that I can work with a client’s technical team to bring state-of-art concepts to bear in solving critical problems.

To help hold down costs still further, I am offering the following options:

  1. Targeted short-course presentation and highly interactive discussion, based on the client’s specific input and instructions of what to cover (requiring substantial additional preparation on my part)
  2. Base rate if a company wants me to present a short-course in an area where I already have materials prepared (toggle down to see list).

Both of these options include any consulting input that I may provide during my visit.  Option A, which I would recommend for most clients, involves an additional $500 per day of course presentation above the base rate (plus travel expenses) that I negotiate with the company for consulting, whereas Option B will be at my base consulting rate for the company (plus travel expenses). 

The following is a list of topics for which I already have prepared extensive presentation material, so I am offering to present these courses without any extra charge beyond my base consulting rate.

Note that if there is interest, I would be able to present either one, two, or more of the courses from the above list, either in full or by selecting material that is likely to be of most critical importance to your company.

Please contact Marty Hubbe (919) 513-3022 (E-mail: hubbe@ncsu.edu) to follow up.

One of the great advantages of having a course at your own site is that we can tailor the contents to match your needs. Based on past experiences, the typical off-campus short course is likely to involve either one or two days of interactive lecture and case-study exercises. Usually it ends up with extensive discussions of how the subject matter can be applied in the client's operations.

The best, most useful courses will require careful preparation, so it is best to give me as much notice as possible. Also, we may have to schedule around other commitments and semester courses. Here are some of the subject areas for which I and my colleages are prepared to give courses at your site:

Opportunities for your company to sponsor research at NCSU can take at least two main forms:

  1. Grant support for publishable graduate research in an area where improved technological understanding is critical to your company. If some of your long-term research needs possibly could be met in this way, CLICK HERE and go to the "Corporate Partners" section of this website.
  2. Technical service work in which the company requests routine analyses, using existing methods to obtain specific, confidential data in the short term. for more information about getting technical service work done, contact Wes Johnson , pilot plant manager. He can be reached at 919-515-7761.

Let us know if either of these areas can help you meet your objectives.
