Comments on: Must Everyone in the Lab Have a Ph.D? http://cstpr.colorado.edu/prometheus/?p=5080 Wed, 29 Jul 2009 22:36:51 -0600 http://wordpress.org/?v=2.9.1 hourly 1 By: Raven http://cstpr.colorado.edu/prometheus/?p=5080&cpage=1#comment-13101 Raven Tue, 24 Mar 2009 11:11:35 +0000 http://sciencepolicy.colorado.edu/prometheus/?p=5080#comment-13101 I think the differences between engineers and scientists is a supply and demand issue. There are too many scientists competing for the available jobs which means the required qualifications have been inflated beyond what may be necessary given the tasks. I suspect a similar credential inflation will occur in engineering as the number of engineers from developing countries with the necessary experiance increases.

It tends to be more important in civil engineering and less important in electrical engineering. Some projects (e.g. bridges) need a PE stamp on documents; many don't. I don't mean to suggest most engineers work in public safety. They don't. It's just that many non-engineers get the impression that engineering education is different from what it is. Engineers with BS's are more likely to be considered engineers than scientists with BS's. That is true. Not only that, but BS engineers often get good, fun rewarding jobs that let them apply what they know in a creative way. This is actually why the education involves more than just training mundane problems. There are so many possible directions one can go with an undergraduate BS.

If you are going to develop a process, or design something new, one of the tricks is to figure out how to turn the development process into a series of appropriate tractable problems and solve each to the level required. Engineering departments do consider what topics are important to the workforce. I'm not sure it's so much that the Engineering faculty are more sensitivity to their students job prospects than science faculty. Maybe they are. I've been on an engineering faculty but not a science faculty. I've always assumed the science faculty do think about BS student's job prospects--- maybe I'm mistaken though. I've always assumed the real difference is that, by definition, engineering is oriented toward application. Industry employs people, and they need people who know how to apply science to make, develop or invent things, develop processes etc. So, to some extent, its a natural consequence for engineering itself to adapt a bit to what industry needs. Science faculty may or may not-- adapting to industrial needs is not inherent to their mission. Anyways, it seems to me that as soon as a scientific field spins off enough applications, you suddenly have a new branch of engineering! In not to large an amount of time, the people doing that branch of science are sudden "Type X Engineers". By definition, those portions of science with the smallest employment prospects for BS students are no longer the focus of the science department.

Science is only running a research program? Then we didn't do science before the 20th century. And I'm not persuaded that your definition of science would allow for anyone in industry to be doing science. There's a presumption here that science only happens at the leading edge, the state of the art. Where does the application of existing knowledge to new phenomena come in? How do you approach research which starts with a lot of observation (such as astronomy)? Science includes drone work. Science includes running experiments, designing experiments, anything associated with the relevant scientific methods for that community. Tying this tighter to the initial post, from a government's perspective, they aren't interested only in producing people to define the questions, but the people who can help find the answers. And there's a lot of drone work involved there. Jon,

The question is asked as to whether a B.S. can "do science." I would answer "yes and no." As an undergraduate, you take foundation classes and mostly read secondary literature. As a graduate student, you do deep into your particular field of interest and get to know the primary literature. So does "doing science" mean doing lab work, or does it mean defining questions? A Ph.D with a faculty job and his/her own lab can "do science" without ever stepping foot into their own lab. Theoretically, they could have a lab tech teach undergraduates the skills necessary to "do the science" in a second meaning of the phrase. If you turn around the question to " can a person with a B.S. do work in a science lab," then the answer is yes, and at Universities many do. Can they get jobs in industry with the skills they develop? Sure, but that's not "doing science," it's just drone work. Ph.Ds are necessary to develop the research programs that put other people to work. Unless you spend the time familiarizing yorself with the state of the art in your field, you don't know what needs to be done and what is likely to be possible/fruitful. Undergrads just don't have the specialized knowledge for that sort of position. The problem is that the kind of job a B.S. is suitable for is not a job that usually leads anywhere. Setting up DNA machines doesn't lead you to running a lab that uses DNA analysis. So why would someone with B.S. want to be a 21st century assembly line worker? I see a problem with the article. The question is asked as to whether a B.S. can “do science.” I would answer “yes and no.” As an undergraduate, you take foundation classes and mostly read secondary literature.

I'm an engineer myself -- I can only hope I count as educated. I'm sure faculty set out to educate their students, regardless of whether they're science faculty, engineering faculty, or anywhere else. There is no mutually exclusive dichotomy between education and training, and I am sorry if I implied otherwise. Also, my "somewhat mundane calculation" sounds like your "tractable problems". Certainly the problems aren't mundane from the standpoint of their relevance to society: "If engineering is the application of science for human benefit, then the engineer must be a student of not only the application of science, but of human benefit as well," and John Prausnitz once said. But, I very much doubt that most B.S. degree holders in engineering ever receive P.E. or EIT certification. Even without these credentials, they stand to earn more than science B.S. holders in most fields, and, in my view, are more likely to be thought of as engineers than B.S. scientists are to be thought of as scientists. I doubt that public safety, narrowly construed, is a majority field of employment for B.S. engineers. Education and training may not form a mutually exclusive dichotomy, but I think there is a difference between them and an important one. My belief, founded only on my own personal experience, is that engineering faculty are more likely to imagine their <i>undergraduate</i> students in some future professional setting, practicing what they've learned as an undergraduate. This thought is more likely to motivate them to modulate, edit, and update course material in response to industrial trends, and more likely to engender a commitment to enforce minimum standards for their students -- i.e. to train them. (I am not saying that scientists don't think their undergrads will get jobs; nor am I saying that scientists don't update or modulate their courses. I am only saying that scientists are LESS LIKELY to draw motivation to do so from their perceptions on how their undergrads will fare in the workforce.) Furthermore, I think the situation is flipped around a bit at the Ph.D. level. I think here science faculty are more likely than engineering faculty to imagine all their students as future practicing professionals and to draw on this image as a source for what to impart to their graduate students. Problem is, scientist faculty's image of a practicing professional scientist <i>more likely</i> to be "PI scientist at R1 University" than an engineering faculty's image of a practicing professional engineer is to be a "PI engineer at R1 University". Look, its hard to make such blanket statements about engineers and scientists when all anyone is bringing to the table is their own experience. If your experience is different, I would love to hear about it. But even more it would be nice to have real data to point to. I did not mean to say that engineers are uneducated.

In my world (natural resources) there are many folks with master's out doing real work. Perhaps all the "applied sciences" are more like engineering. Mostly they are in the world of applying scientific information, not generally producing scientific information in the peer-reviewed literature. In fact, there are many people with Ph.D.'s who are involved in the application world (including myself) for a variety of reasons, including the fact that there aren't enough jobs (or research funds) in research, but also due to less-desirable factors about worklife, at least in universities. Who is a scientist is definitely worth discussing, for nothing else if we are not clear on what a scientist is, how can we make sure they are adequately involved in policy?

My general impression is that somehow employers and even the general public think that only someone with a Ph.D. has ‘credible levels’ of knowledge in the science fields. I do believe there are a few basic reasons this occurs. First, when news outlets or congressional panels what experts they seek out people on the top of the food chain which will always be Ph.D. holders with years of research experience. So the perception of those seeing a news story or watching a hearing becomes conditioned to Ph.D. being a required moniker for knowledge in the sciences. Second, there are few methods for scientist to be tagged with a level of ability and knowledge outside the degree process. There are some, for instance the American Meteorological Society does have the Certified Consulting Meteorologist program. However most engineers, if they want, can become a Professional Engineer if they decide they want to stay in the field. That type of certification also requires work experience. So practical application of skills learned in school is required to achieve a certain level of status. Third, most pure science work is done in major universities and government labs in the US. Again there are a few exceptions, but the general arena for that type of work is for employers whose traditional systems for recognition are based on degree levels. In going back to graduate school for a degree in the sciences and coming from a different arena previously, I was struck by this system that many in the business world or just outside academia in general would be find puzzling. I met many undergraduate students with exceptional skill and ability that would likely not pursue a graduate degree because they had no real desire to spend 5+ years getting a Ph.D., yet they felt without it any time in graduate school would be wasted. I think that until there is a system in place that recognizes the skill and abilities in some way besides just these three monikers: B.S., M.S., Ph.D. that the problem will continue.
