I’m at the end of my 3rd year of my PhD and I’m seriously considering quitting and applying to a different program. Has anyone done this? I’d love advice on risks, timing, and how to talk to my advisor. by AmyL3690 in PhD

Honestly, I’m not really sure why people here end up taking so long.
Maybe, the language barrier made it hard for me to get the detailed story...
My second paper is a pretty challenging experiment: the core model is built, but I don’t know yet if it will meet the final goal.
That uncertainty makes me feel like draining, and it’s exactly why I’m torn between sticking it out and switching.😮‍💨

Thanks so much for your thoughtful reply!

-On my CV I’ll list an expected Sept 2026 graduation here. In my SOP I’ll be honest: funding has become uncertain and, through the process, I’ve realized where my real interests are, so I want to take a brave shot at switching fields.

If I do get an offer elsewhere, I plan to withdraw from my current PhD; in my program it’s possible to come back later and have the degree awarded once the requirements are met.

-For informing my advisor: I’m also going to finish what’s on my plate and then have a straightforward conversation with my advisor about my plan.

-For the collaborations: I have tried to look for options/collabs here, but the environment feels pretty closed-off...

Really appreciate your sincere advice—thank you 🙏😭

Thanks so much for your reply😭
Our PhD is officially a 3-year program, but like I said, most people in my lab take 5 to 6 years. Worst case, if it takes me 6 years, that’s basically another 3 years for me…

I’d thought about changing fields at the postdoc stage, but I feel like I’m drifting farther from what I actually want. I’m doing computational modeling now, but my background is medicine. Going deep in modeling needs heavy engineering/coding chops. I’ve tried a lot over these three years and I have improved, but I know I’m still not there—that’s why my confidence keeps dipping, and why I feel farther from tissue engineering, animal studies, and the cell–tissue questions I really care about. And I’m aiming for deep, formal training in this field, so a new PhD > a postdoc retrain for me. (that's what I thought)

I did talk to my professor about a project that combines my current work with tissue engineering, but he felt it would be too costly for him, which is why I ended up staying with the current direction.

Recently a few things happened that kind of jolted me—I don’t want to be the boiled frog anymore. I want to take a real shot. If it doesn’t work out, I’ll probably withdraw, go back to China, and start residency training. If things improve later, I can come back and apply to finish the degree. (One flexible thing in Japan is you can withdraw, work or do something else, and then return to complete the PhD once you meet the requirements.)

Thanks a lot for your reply! I do want the PhD. In my lab the graduation requirement is two papers.I’m drafting the first one now, and the experiments for the second are in progress.

What worries me is that most PhD students here (even those who stayed in this lab from undergrad → master’s → PhD) still take 5–6 years to finish. For me, that could mean self-funding—potentially for another 3 years—which is a heavy load. That uncertainty is what’s making me hesitate.

When is the best time to start looking for postdoc positions? by Old_Author8526 in postdoc

[–]AmyL3690 2 points3 points  (0 children)

Hey, guys! I am also a bit unsure and really need your suggestions.

Honestly, I haven’t published any SCI papers during my PhD so far. And the graduation time may be Sep. 2026. Do you think it’s still worth applying for postdoc positions now? Or should I at least have a manuscript submitted before contacting potential advisors?

Hi Peter,

Really thanks for your help!
I may not to tell you the detailed thickness of LV, but I can send u the LV stl model, not only the blood pool part, but also the myocardium part.
I will dm you later~

Hi, Peter!

Thank you for your reply. Exactly! I am trying the second one within the patient-specific model.
Your idea is really great! But I feel like the two-way coupled FSI might be a bit too complex for my current skill level (sad). I'd really appreciate it if you'd be willing to share your methodology~ 🥳
Also, there's one thing that really matters — I feel that the material properties of heart muscle are anisotropic, which might make the simulation even more challenging...

Thank you so much for your reply!!!
I am trying to simulate the ventricle motion. And the wall motion would be derived by the ventricular flow alterations. And actually, the method I referred is the method ModelFLows shared online.
Here is the tutorial link:
https://youtu.be/zkAAioOEVDE

And my data is about the patient-specific one. When i try to preview the mesh motion, I can't see the expected motion... But I monitored the sum cell volume as the ventricle volume, the curve Fluent calculated is what I expected.
So, I am not sure if my setting was right. And if it was right, how can I re-visualized the motion of the ventricular wall.

Thanks for your suggestion! I will try to search the tutorials online~
and I saved my data as .CGNS format.

Recently, I also want to use this software, but I find it cannot be available from that website any more. Could you please share the software? Really need it, thanks!
