Narrative:
While climbing to FL310, light to moderate turbulence was encountered around FL280. In an attempt to expedite the aircraft through the turbulence I rotated the nose up to trade airspeed for altitude. Turbulent conditions still existed at FL310 and while leveling off at our assigned altitude of FL310 the airplane's nose up (more than normal for climb) attitude and the turbulent conditions resulted in an altitude deviation of 400 ft. FL314 was the highest momentary altitude reached. ATC did not query our altitude, nor was there a TCASII warning. Supplemental information from acn 393415: I warned first officer at FL290, FL300 and FL305 about his rate of climb. First officer did not respond to my input until FL308, overshooting FL310 by 400 ft. He then overcorrected and descended to FL307. First officer later stated he was uncomfortable with me giving him input on how to fly the aircraft. He did not use clear and verbalize this to me due to his military fighter pilot background. I thought he could handle the rate of climb and failed to take control of the aircraft to prevent the altitude overshoot.

Title: AN MLG ACFT EXCEEDS ALT AT LEVELOFF BY 400 FT IN ZLA, CA, AIRSPACE. PF RESENTS THE PNF TELLING HIM HOW TO FLY THE ACFT.
Narrative: WHILE CLBING TO FL310, LIGHT TO MODERATE TURB WAS ENCOUNTERED AROUND FL280. IN AN ATTEMPT TO EXPEDITE THE ACFT THROUGH THE TURB I ROTATED THE NOSE UP TO TRADE AIRSPD FOR ALT. TURBULENT CONDITIONS STILL EXISTED AT FL310 AND WHILE LEVELING OFF AT OUR ASSIGNED ALT OF FL310 THE AIRPLANE'S NOSE UP (MORE THAN NORMAL FOR CLB) ATTITUDE AND THE TURBULENT CONDITIONS RESULTED IN AN ALTDEV OF 400 FT. FL314 WAS THE HIGHEST MOMENTARY ALT REACHED. ATC DID NOT QUERY OUR ALT, NOR WAS THERE A TCASII WARNING. SUPPLEMENTAL INFO FROM ACN 393415: I WARNED FO AT FL290, FL300 AND FL305 ABOUT HIS RATE OF CLB. FO DID NOT RESPOND TO MY INPUT UNTIL FL308, OVERSHOOTING FL310 BY 400 FT. HE THEN OVERCORRECTED AND DSNDED TO FL307. FO LATER STATED HE WAS UNCOMFORTABLE WITH ME GIVING HIM INPUT ON HOW TO FLY THE ACFT. HE DID NOT USE CLR AND VERBALIZE THIS TO ME DUE TO HIS MIL FIGHTER PLT BACKGROUND. I THOUGHT HE COULD HANDLE THE RATE OF CLB AND FAILED TO TAKE CTL OF THE ACFT TO PREVENT THE ALT OVERSHOOT.
