| 1 | +# Frequently Asked Questions |
| 2 | + |
| 3 | +This document addresses common questions that students and researchers in our group often have. |
| 4 | +If your question isn't answered here, please reach out to Spencer or other members. |
| 5 | + |
| 6 | +## General Questions |
| 7 | + |
| 8 | +### What is the focus of the Computational Physics Group? |
| 9 | + |
| 10 | +Our group focuses on developing computational models and numerical methods for physics problems. |
| 11 | +We accompany our methods with algorithms crafted to make efficient use of the latest exascale machines and computer architectures, including AMD GPUs, Arm/RISC CPUs, and quantum computers. |
| 12 | +We develop open-source software for these methods that scales to the world's largest supercomputers. |
| 13 | +Our work pushes applications forward in areas jet and rocket design, defense broadly, medical therapies and physiology, and the energy sector. |
| 14 | + |
| 15 | +### How do I join the group? |
| 16 | + |
| 17 | +Visit our website at https://comp-physics.group for information about openings. |
| 18 | +Messages to Spencer that do not follow the website instructions will be ignored. |

| 20 | +## Research and Collaboration |
| 21 | + |
| 22 | +### How are research projects assigned? |
| 23 | + |
| 24 | +Research projects are typically assigned based on a combination of the group's current research priorities, funding availability, your interests, and your skillset. |
| 25 | +We try to find a good match between these factors, and there's often room for you to propose your own ideas within our broader research themes. |
| 26 | +Our current research includes multiphase flow solvers, stochastic models for cell-scale flow, and information geometric regularization for extreme scale compressible flow simulation. |
| 27 | + |
| 28 | +### How often do we have group meetings? |
| 29 | + |
| 30 | +It ebbs and flows, depending on the interest of the students. |
| 31 | + |
| 32 | +### What software/programming languages should I know? |
| 33 | + |
| 34 | +Proficiency in one high-level and one-level language is important. |
| 35 | +We often use Fortran (free-form) as a low-level language, but new projects may be more ammenable to C/C++. |
| 36 | +High-level languages are mostly up to you, though I prefer you use Python to maximize the reach of your software. |
| 37 | +Our group develops widely used open-source software like MFC, an exascale multi-phase flow solver. |
| 38 | + |
| 39 | +## Academic Progress |
| 40 | + |
| 41 | +### What are the publication expectations? |
| 42 | + |
| 43 | +PhD students generally author or co-author 3-5 papers during the program, with 1 or 2 as first author. |
| 44 | +The quality of publications is valued over quantity. |
| 45 | +See the [Publishing](publishing.md) guide for more details. |
| 46 | +Our group regularly publishes in high-impact journals and conferences in computational physics, fluid dynamics, and related fields. |
| 47 | + |
| 48 | +### How do I know if I'm making good progress in my research? |
| 49 | + |
| 50 | +Feedback should be provided during one-on-one meetings, but if you have any questions or doubts you are *strongly encouraged* to talk to Spencer. |
| 51 | +Generally, good progress includes advancing your research questions, developing your technical skills, producing results (even negative ones), working toward publications, and __becoming an independent researcher that does not need Spencer__! |
| 52 | +Of course, I understand research has natural ebbs and flows. |
| 53 | + |
| 54 | +## Resources and Support |
| 55 | + |
| 56 | +### What computing resources are available? |
| 57 | + |
| 58 | +Our group has access to various computing resources, like Georgia Tech's PACE cluster and external supercomputing facilities. |
| 59 | +See [Available computers](computers.md) for specific information. |
| 60 | + |
| 61 | +### Is there funding for conferences? |
| 62 | + |
| 63 | +Yes, attending conferences is an important part of academic development. |
| 64 | +Funding is often available for students. |
| 65 | +See [Going to conferences](going-to-conferences.md) for the process of requesting conference funding. |
| 66 | + |
| 67 | +### What should I do if I'm struggling with my research or coursework? |
| 68 | + |
| 69 | +First, know that challenges are normal in research and graduate studies. |
| 70 | +Reach out to Spencer for research difficulties or course instructors for academic challenges. |
| 71 | + |
| 72 | +## Work-Life Balance |
| 73 | + |
| 74 | +### What are the expectations for working hours/days? |
| 75 | + |
| 76 | +I value productivity over specific hours worked. |
| 77 | +While I expect full-time commitment during normal workweeks for funded students, I'm flexible about when and where you work. |
| 78 | +See [When and where of working](when-where-working.md) for more details. |
| 79 | + |
| 80 | +### Can I take vacation time? How much? |
| 81 | + |
| 82 | +Yes, taking breaks is important for maintaining productivity and mental health (at least for most folks). |
| 83 | +Typically, students take 2-3 weeks of vacation per year, plus university holidays. |
| 84 | +This is flexible, so just talk to Spencer and coordinate with Spencer in advance, especially for longer absences. |
| 85 | +You may find yourself taking semi-vacations, where you aren't in town but find yourself doing some side-work for fun anyway. |
| 86 | +This is up to you. |
