We've been away for a while I have for sure. But I am back with a very great friend of mine, tool gunner, and I am happy to introduce him to you what a legendary man he is. He has okay. Oh, you know what? I'm not gonna give you the introduction. I'll let him introduce himself the way he he sees fit. Hey, Joe, how are you doing? Tugrul 00:43 I'm good, by the way, are legendary? Pouya LJ 00:48 No, no, I know you well enough to give you that, you know, give you that adjective. So that's all well deserved? For sure. All right, turtle. So why don't you give us a very brief but comprehensive background about yourself, the way you see yourself from your academic background personally. Yeah, go ahead. Tugrul 01:10 Yeah, sure. Sure. I will start with when everything changed in my life. I was like, I was not cared about anything before, like last year of my high school. So I was like, playing video games going out like playing soccer. And the classes were like, I wasn't. I had zero interest at all. But I wonder I was reading a lot. I was like, I was kind of reading lots of different books, different types of books, mostly like fantasy books, like Dragon land series, forgotten mediums. It all started with a lot of things by the way. Yeah, anyway, but that was also another story. My father, like, gave that present to me like a lot of drinks book. But the second book, he just grabbed a random book from there probably, like, just grab the second book. And then I Oh, what's this looks let me read the first one. Then I started with the Lord of the Rings. Okay. But back then I was reading this Dan Brown's book called demons and angels, or whatever. Demons. Pouya LJ 02:22 Read the book, but I've watched the movie. Okay. Tugrul 02:24 Yeah, I also watched the movie, but I don't know. Like, it was a good book. I'm not sure. But the thing that just like was interesting to me when they were talking about like, antimatter. So I just, like stuck at that point, like, Oh, my God, what is this? Like, I never heard of this before antimatter. Like, I wasn't even interested in physics. Okay. No, no, no, no, but antimatter was like, something changed. What? I never heard of this before. And I realized that I mean, we have lots of things we don't know. That was the, like, a break point in my life. Okay. We're, we're just pretending that we are we know stuff that based on our observations, these are like a micro sis macro systems that we are observing daily, like mostly, like, wearing like an eternal outdoors, we all know, so we just ever have that. Like, I mean, if you drop something, it just falls down. Like it's a gravity, I mean, this kind of stuff. But I that was something different. You can observe it you need to be in that field to know what is antimatter. So that was a some kind of like, a break point in my life. Okay, then, I started to read a couple of things about it, then I noticed that oh my god, this is something else. There's another world inside of this like, like quantum mechanics, even though I had no idea what quantum mechanics is, but I was like reading uncertainty principles, something is not clear. But something sounds are like, interesting, like, Oh my God, what's happening here, like the universe is not really like, observed something more and more. I mean, then, last year, in my high school, I develop interest in the physics as you expect, like, then I was like, for the my bachelor degree, I have to study physics. And I have to I have to become a theoretical physics physicist. I mean, because I really wanted to understand everything. That didn't happen, of course, but I'm gonna mention that I'm going to talk about it. So So I in in my country, for bachelor's degree, you have to take an exam and after the exam, you need to write the university and discipline like this university physics. This university for example, electrical engineering Pouya LJ 05:00 to give his background so when you're originally from Turkey, so you do your Bachelor's there. Yes. Okay. Go ahead. Tugrul 05:10 Yeah, yeah, my masters and PhD there too, but Right, so, so you have limits, of course. So you can just write 20 University and 20 different subnets. So I wrote physics for all of them. Because I was like, obsessed. So, yeah, I just got into physics. But it was kind of disappointing. Like, okay, I was kind of, I mostly like, thinking about this ideas, thinking about how universe should work. And this kind of like a philosophical way of Lego discussions, I've kind of mostly like that way of it. But mathematics. When it starts to become complicated, you start to lose control of your thoughts. Also, sometimes, like, if it gets too complicated, you start to focus mostly on the mathematics to solve that problem. You're getting away from your first idea, and you can find yourself with into different concepts, different mathematical tools. Of course, it can guide you different discoveries, of course, but you need to, you need to have that skill to have fun with this mathematics. I didn't have that one. So still, I was like, kinda stubborn. So I wanted to do my master's degree also in physics, which did the quantum mechanics from from the fundamentals, which was focusing on the foundations of it like, main things like fundamental things. So we published a paper about quantum tunneling. Because there was a problem about estimating time in quantum mechanics. And tunneling is a phenomenon that happens in time, even though there were people that researchers like arguing about maybe instantaneous, maybe it's not time dependent, but we found the time for that, which we published. It was a nice journey for me, but then I changed my topic, like, very like a, like a 100 watt, like 180 degrees, like, just back with like, a different direction. Which I started doing my like a PhD in material science and engineering, talking about the relevant components. Pouya LJ 07:35 The way you say. It was 180 degrees deviation. One would think this is a you went to art since fallen artists. No, I'm kidding. Within the realm of physics, you didn't want it okay. Yeah, Tugrul 07:51 I mean, like, change my direction, like, I mean, it all you can also call it 90 degrees to I mean, I was just like I did, I was like, spanning somewhere else. Yeah, I started to work on some applications. I was kinda materials, material scientist, I was working on polymers, polymer composites, emissive materials, like I was mostly working on alternative materials for the white LEDs, because in LEDs, especially white LEDs, you were using phosphorus, which they contain, like rare earth elements. So I was trying to develop new materials or trying to increase the efficiency of the this phosphor materials inside the tube. It was nice, it was a efficient pH like I published like kinda 20 papers, because it's an application is not a theoretical physicist. So it was kinda like it's highly liked, like you can publish papers, as long as you develop something and you showed us an increase those improvement, it works. Or you even you can come up with a new material, which we were there was like a sample. One kind of material was very popular back then we even published a couple of papers awarded called halide perovskites. Yeah, so I was kinda like optimistic about my postdoc. Because like, 20 papers, so I was like, okay, I can find a good postdoc position around the world, but it didn't go that way. I applied like 600 700 positions with a detailed applications. I didn't get a response from most of it. Probably some I didn't even send the second secondary email to them, but probably they went and noticed, like one of them just, he's a Turkish professor. Also, he's a professor in Montreal, Pouya LJ 09:59 Montreal. Canada, yes, Tugrul 10:00 that's Montreal in Canada. So that's he sent me like the position and offered me the postdoc position, which was an amazing subject. It's called water fast electron transmission electron microscopy, which transmission electron microscope by itself is a characterization tool that can image materials at nano scale, which is like 10 to the minus nine is like, how much like 1000 Lower magnitudes higher magnitudes than the human hair, right in 1000, it was micron, so, probably around 1000. Similar things from the human hair. Even more, I don't know, like, probably some that kind of scale. So we were basically imaging nanomaterials at the Nano scale, like we were characterizing them trying to understand the shape some of the properties, but this is regular transmission electron microscopy, ultra fast transmission electron microscopy is where you are integrating your microscopy with laser. Now, you don't only have this imaging, you also have this laser, which you can also send it to your material and observe what's happening when your metal or nanoparticles are interacting with the laser. Which brings, we call it the time dependency for your observations, which is from imaging, a now you start to record movies, and you can visualize what they're doing and understand the interaction of places in time. So, by the way, my professors professor in Caltech, his name was like Zewail, he, like, got the Nobel Prize for this invention, mostly, you got the Nobel Prize for t
