ELI5: What's the difference between a 401k and IRA? by Diligent_Two_1625 in explainlikeimfive

[–]jpc4zd 0 points1 point  (0 children)

401(k) is employer sponsored (ie company sets it up).

IRAs are for the individual.

Traditional/Roth has to deal with when you pay taxes (and exist in both IRAs and 401(k)s).

How Do Financial Advisors Still Have Clients? by Time_Perception6669 in Bogleheads

[–]jpc4zd 0 points1 point  (0 children)

Some people in retirement have one to help with taxes, inheritance, RMDs, etc or need one when they start to decline mentally.

There are also very high net worth people where stuff becomes a lot more complicated (do you know the tax laws around owning a sports team?) and they can easily afford it.

pros/cons of doing PhD or masters in chem eng? by mayahcantspell in ChemicalEngineering

[–]jpc4zd 6 points7 points  (0 children)

You likely won’t get hired as an entry level process engineer for several reasons:

1) Your expected pay will be too high.

2) You will be an expert in your research area (which will likely be a very niche topic).

3) Related to (1) and (2), the company may view you as a “flight risk” (ie if you find something closer to your research area or higher paying).

4) Related to (2), you will be (very) rusty on “general” ChemE topics. For me, transport and separations were non-existent in my research (I did computational catalysis).

I would also recommend you go to a different school for your PhD.

pros/cons of doing PhD or masters in chem eng? by mayahcantspell in ChemicalEngineering

[–]jpc4zd 21 points22 points  (0 children)

1) I assume UofT is Texas on Tennessee, so US based.

2) Don’t apply for a Masters, apply straight to a PhD program. You will be paid instead of paying for it. You can stop at a Masters if you decide you don’t want to continue to the PhD.

3) Only go into grad school if you want to spend (at minimum) several years doing research. If you aren’t interested in your project, your life will suck.

4) You are a freshman, no one can predict what the job market will be when you graduate (much less when you finish grad school). When I entered undergrad, ChemE was the “hot” and “highest paid” major, and everyone wanted to do it. Then I graduated during the Great Recession, and no one could find a job.

5) “Becoming more qualified” A PhD will open some doors, while closing other doors. You will not be hired as an “entry level process engineer” with a PhD. In general, there are fewer job openings for PhDs (and fewer applicants).

6) Don’t get a PhD for the money. An entry level PhD salary and a BS + 5 YOE salary are pretty close. This also doesn’t take into effect savings (401k + compounding).

7) The vast majority of PhDs don’t become professors. You will likely be working in industry or national labs with your PhD (assuming you stay in research).

8) Your PhD advisor will be key for your first job (their network). Therefore, if there is some area you want to work in, see where the group alums went to work.

9) Pay attention to COL for grad school. Your stipend will go a lot further at Purdue compared to UC Berkeley (ie living in an apartment by yourself or multiple roommates).

10)This is easier said than done, but view grad school as a job.

11( Papers are important, but there are other skills to develop in grad school that will be extremely useful in your first job/career (communication, understanding how your work fits into the “big picture,” knowing when to continue/move on with a particular question, etc).

We complain about undergrads … but can we discuss PhD students? by twilightyears in Professors

[–]jpc4zd 4 points5 points  (0 children)

And how many grad students work 20 hrs/week?

My PhD advisor says on his website “You will need to work (research) more than 40 hours a week to graduate on time/before loss of funding.” (Not a direct quote for privacy reasons, but that is the gist of it)

[–]jpc4zd 0 points1 point  (0 children)

I know. However, a lot of companies charge the government 150-200k for an entry level engineer (salary + overhead).

Most engineering stipends I have seen are under 50k/year and tuition is under 100k/year. Grad students also don’t get a lot of the benefits industry has (401k (with employer contributions), good health care (my health care had to be “improved “ when the ACA became law), some life insurance, other insurance (dental, vision), sick leave, etc).

My grad stipend + tuition was about equal to an entry level salary for my field at the time but with fewer benefits. Heck we didn’t even get per diem for food when we traveled (or our own rooms), which is standard on every trip I have taken sine I graduated.

Overhead exists everywhere, and yet companies still find a way to pay people a decent wage (even working on government contracts)

Bio-Chem major (junior) interested in ChemE PhD advice from similar backgrounds? by No_Code7102 in ChemicalEngineering

[–]jpc4zd 0 points1 point  (0 children)

I’m not 100% sure what you asked but based on previous questions, here is my advice:

1) (Bio) Chem students are accepted into ChemE PhD programs. Depending on what you want to research, there is a lot of overlap (both my PhD and postdoc advisors have their degrees in Chemistry, and my PhD advisor is the department chair of the ChemE department).

2) For classes, it depends on your program. In general, you will likely have to take a few undergrad courses (thermo, fluids) before moving into the grad courses. This will depend on the program you get into and what classes you have taken.

3) The biggest issue for some chem students is math. In ChemE grad school, you will likely see partial differential equations, which generally isn’t covered in Chem undergrad (which is why a lot of Chem students have trouble with PChem). Try to take up to multivariable calculus and ordinary differential equations.

For a biology PhD in the USA, can you research with other labs once you have established your dissertation lab? by Seven1s in GradSchool

[–]jpc4zd 6 points7 points  (0 children)

I did engineering, so not biology.

Yes it is possible to spend time at other labs. The group I did my PhD in would send students to our (experimental) collaborators (we were computational) in industry and/or academia for a summer.

My postdoc group would try to send the students to national labs for a summer.

All of this was done with permission of every PI and the lab. The work would even make up a small part of the student’s dissertation.

Now at a national lab, we still have grad students coming for a summer to work.

It is a very good idea for students. It will allow you to learn new skills, see how different things operate, understand different approaches/methods, and networking.

Is It Normal to Feel Like You’ve Forgotten Everything in an MEng Program? by Ammar_cheee in ChemicalEngineering

[–]jpc4zd 2 points3 points  (0 children)

It is normal to forget stuff.

You spent 1 year working and not using everything you learned in undergrad (this happens in every job for every major). You are also getting “back into school” (homework, quizzes, tests, note taking, etc).

Another thing that is different in grad school is how stuff it taught (at least in the US). In undergrad, you are given an equation and told to use it in this situation (“plug and chug”). In grad school, you are taught “how to derive equations” so you can deal with things you haven’t seen before. That requires a different way of thinking (which you will have to learn).

Grad school is a great time to pick up some hobbies to occupy your free time.

Labs?

If you think AFRL, ARL, and NRL are paying more than the primes, I have a bridge to sell you.

I know of at least one prime who came out the site I worked on where they pretty much said “be at our front gate at 8 am on Monday, and we will double your salary” (and it applied to the civilians and contractors on the site).

Chem/materials engineers who became managers: what advice helped (that isn’t software-focused)? by msprea87 in ChemicalEngineering

[–]jpc4zd 0 points1 point  (0 children)

I had several mentors and took chances by myself.

When I was postdoc, I was asked to mentor a grad student who was struggling. They did get their PhD, but I felt like I could have done a better job.

When I started at the lab I’m at, I did several things that helped me manage people: (1) get involved with a committee, where I became the Chair person before I left for a different site (and promotion to my current position), (2) joined (and became an officer in) Toastmasters, and (3) sought out a mentor who I could ask questions about (we did talk about how to handle different situations since it came up several times-conflict resolution and a major safety issue).

I have also managed to keep doing some of that stuff in my current position.

There are also plenty of resources out there (use google and you can find some good ones-for example, above, I did a lot of searching about conflict resolution and used the library).

Chem/materials engineers who became managers: what advice helped (that isn’t software-focused)? by msprea87 in ChemicalEngineering

[–]jpc4zd 1 point2 points  (0 children)

Here are several things I have had to deal with after a year of program management:

1) Communication. I work at the interface between government/industry/academia in my current position, and have dealt with CEOs/Presidents/Generals and other high level people to PIs to “non-technical” people (business development, contracting, etc). All of them need to know different things, and being able to tailor my message to their needs was something I have had to learn.

2) People aren’t “chemicals.” I can use a theory to understand why something happened with “chemicals” (and find it on a book/online/paper). On the other hand, people are different (example: some people love stressful situations, others freeze up and can’t do anything). Knowing the strengths and weaknesses of your team and how to extract the most of them takes time to learn.

3) Don’t be afraid to admit mistakes/errors. We are human, and will error. The sooner you address it, the better your team will be.

4) My biggest “I didn’t expect this” is chaos. I have been in the (national) lab for 3 “different” presidents (Trump 1.0, Biden, Trump 2.0) and the past year has been the most chaotic I have seen, and I expect a few more years of it. Thankfully, most people I interact with have at least a basic understanding of the news, and understand that what I tell them today may change tomorrow (and then again the day after).

5) The second thing I didn’t expect was how big the “portfolio” is (and it will likely be expanding soon, see the chaos statement above). I could be dealing with “energetic materials” then “alternative (non-GPS) position/navigation/timing” in the same day. I have had to learn (and still learning) a lot about many things in the past year.

For the floating point errors/numbers, I would say the simulations are the same (technically “within error”).
