Research

• I am actively working on several projects in inflationary cosmology and f(R) gravity.

• I am a Research fellow at the COST Actions; CA21106: Cosmic WISPers, and CA21136: CosmoVerse.

  After having a course at university about Topology, I did an elaborated research in this part of math, and felt the urge to write something like a notebook that will give students, specifically, undergraduates of Theoretical Physics, Cosmology, and Mathematics, an idea of the basics and theorem that will assist them the perceive the main theme of Topology. You can download it by clicking here.
  

• Rafid H. Dejrah, "Quantum Mechanics"
  

  This is a summary of my notes for a broad introductory and advanced courses in the field that I assume it might be a good starter for the newers in the field. I highly gave a top priority for the regressive Mathematics, which will help the reader to have a better and clear image of this field.

Our department is supervising the publication of a journal that is related to physics, in the first volume, I was one of the first students who published a reviewed article about the eveloution of our universe.

Awards

I have been very fortunate to be awarded prizes for both my research and my academic efforts in recent years by which I have the chance to be more stable in my life and give physics my maximum concentration.

• Erasmus+ Grant
• YTB-IsDB Scholarship.

Talks

• Gave a talk titled "Minimally coupled β-exponential inflation with an R² term in the Palatini formulation" at the COST action: CA21106: Click here to access the matrials of the talk.
• [2024] Gave a talk titled "Further analysis on metric-affine f(R) gravity"
at Laurentian University.

I have given many public talks to a diverse range of audiences. I particularly love to share my passion with others. Moreovre , I do present topics related to the fields of my interests at experts-oriented programs, summer schools, etc. If you'd like me to give a public lecture please get in touch with me using the button below.

Frequently Asked Questions

This section is still under construction

Time as a theoritical physics student, and a researcher at the same time is a more precious resource than I ever imagined. As such, I can be kind of hard to contact. If you are trying to find me to talk about something, email is my preferred method --- it gives me a chance to defer answering until I have a chance to respond thoughtfully to whatever you might be asking.

• Telephone: I don't answer my phone when I'm in university unless I recognize the caller on my caller ID, and I'm not busy with something else. I generally hate receiving unsolicited phone calls --- if I'm at campus, I'm working, and I don't appreciate being interrupted.
  If you would like to speak on the phone, please send me an email and set up an appointment first. I hate acting like such a prima donna, but I can't get anything done unless I control my schedule very carefully. (As one of my colleagues likes to say "I have lots of free time; it just all comes in 5 minute blocks.")


• Brilliant theories: If you have found the Ultimate Theory of the Universe, discovered how to tap into the energy of the vacuum, or have found the meaning of life in the pattern of hotspots in the cosmic microwave background, I'm very happy for you, but I really don't care to hear about it.


• Science questions: If you are a student with a question that you think I may be able to answer, I am generally happy to do so. An example of a question that I am likely to answer (though it may take me a few days to clear out enough time to do so with care) is
  
  I'm a high school student doing a report on black holes. If you could help me to understand the following thing I read about, I would really appreciate it.
  
  A bad example is
  
  Hey dude, I was wondering about black holes. Could you like tell me about them? Oh, and could you send me a 1 page single spaced answer by like tomorrow at 8 am? That's when my report is due.
  
  I'm very sad to report that the bad example is based on a real email I received (albeit I've improved the spelling and grammar).
